Talk: Photos and video taken on an aerial summit tour around the upper reaches of Alaska’s Denali (formerly Mt. McKinley) in 2008 show the terrain of the Mountain and historic climbing routes. Photos of parts of the route used by the tragic, controversial 1967 Wilcox expedition illustrate the challenges to climbers of Denali’s terrain and its extreme weather conditions.

January Section Meeting “CoFe-based cylindrical nanowires”
Monday January 18th, 2016, 11:45 AM
Lecturer: Professor Manuel Vazquez, Madrid Spain
Location: Promega BioPharmaceutical Technology Center Room Number: 216/7 5445 E Cheryl Pkwy Fitchburg, Wisconsin
The recent interest on the magnetization reversal process of novel families of nanowires originates in the need to have full information about their magnetic properties for different functionalization and technological applications. The electrochemical route to fabricate nanowires is attracting much interest owing to their low-cost and reliability to fabricate tailored magnetic nanowires and nanotubes. This technique enables the synthesis of nanowires with cylindrical symmetry in opposition to nanostripes prepared by lithography techniques. Arrays of such nanowires can be grown with diameter of 15 to 200 nm, and length from 100 nm up to tens of microns. Cylindrical nanowires can be also grown with compositional multisegmented character and with controlled modulation in diameter intended to play a similar role as notches in lithography nanostripes. The particular study of Co-based nanowires is relevant since their magnetocrystalline anisotropy, in opposition to Py nanostripes, plays an important role to determine the magnetization reversal mechanism by vortex or transverse domain walls and spin rotation modes.
Most recent results in our laboratory will be overviewed specially focusing on the spin reversal process in Co and CoFe individual nanowires after their release from porous templates. Knowledge of the fine crystalline structure, through high resolution transmission electron microscopy and other advanced techniques, is essential to determine the magnetocrystalline anisotropy and the spin reversal process.
Professor Manuel Vazquez was born in Madrid, Spain. He was awarded a PhD in Physics by the University of Madrid, 1980; had post doc stays at Max-Planck-Institute fuer Metallforschung, Stuttgart (1981-3) and at the Technical Univ. of Denmark, 1985. He was Associate Professor at Madrid University, 1985-1989, then, he moved to the Spanish Council for Research where he became Research Professor in 1996. He is presently heading the Research line of Nanomagnetism and Magnetization Processes at the Institute of Materials Science of Madrid, CSIC. His main scientific interests lie in the topic of Magnetic Nano- and Microwires, with particular emphasis on the magnetization reversal processes, domain structure and domain walls, and magnetic anisotropy (i.e., magnetostriction). With more than 400 publications, co-authoring of 9 chapter books, and about 20 patents, he has given over 70 invited talks in international conferences and research centers, has supervised about 30 PhD and hosted a number of international visitors.
His most recent interest is overall related to the development of three-dimensional magnetic nanostructures by combined electrochemical/lithography techniques, and to unveil the magnetization reversal process and domain wall structure in individual and ordered arrays of magnetic nanowires and nanotubes as well as of antidot thin films. Research efforts are being addressed to the study of Co base cylindrical nanowires/nanotubes where the tunable magnetocrystalline anisotropy plays an important role.
Review of December Events
December Section Meeting “Audio and Computer music in the Present Age“: (Review by Charles Gervasi) Greg Taylor’s talk was called “Campfires Seen from Orbit” because it approached the subject from a philosophical view of how electronic music fits into music over human history. When Max, an early music creation software, started 36 years ago, it required a whole room of computing equipment to run. Now it runs easily on a laptop, making modern musicians think of a laptop as an essential musical instrument. New technology tends to affect music in unforeseen ways. Originally someone put a microphone on a guitar to make it louder. Imperfections like clipping or feedback became part of music and became more important than the original purpose of adding a mic. There is a modern type of music called Congotronics that uses older electronics repurposed playing traditional music from the Congo in completely new ways.
Taylor talks about the broad question in technology of “what’s the next big thing?” As engineers we want to know because have an interest in cutting-edge technology and there’s potential for great wealth. Taylor says the question is based on a false premise of a linear progression of technology. There is no “next big thing”. We have access to things down “the long tail”, not vetted by gatekeepers, and not geo-local. The talk touched on chaos theory of “attractors”. Starting with the phonograph, music has been getting easier and cheaper to record and transmit, making it seem natural for music to be free. The perception of the cost of music is affected by the cost of the media. Every new development in music technology influences music in unpredictable ways.
There are countless new pieces of musical hardware and software people are creating and sharing on the Internet. Taylor showed us an example of a keyboard with lights that is really nothing more than an I/O device for a computer that lends itself to music. There are musical instruments that run entirely on a tablet computer. In one example, the musician can drag things around on the screen to change the nature of the sound. In the past musical communities formed to develop music. They admitted or rejected people based on certain aesthetic judgments and biases of the members. These musical communities have gone online. They serve the same purpose as musical communities throughout human history except everyone can join regardless of initial judgments of members, opening music to people who in the past would have not been part of a community. This will affect music in unknown and exciting ways.

December ECN Meeting:
Was held on Thursday, December 3rd and included free pizza and snacks It was a social/professional “Meet and Greet” where attendees shared their background and had an opportunity to pitch what it is they do. Topics ranged from manufacturing temperature probes in China, to not exporting jobs to China. There was a particularly lively discussion of software job opportunities ranging from “I need one (Software Development)”, to “My job was exproted to India (database Programming)” to “I see opportunities for the foreseeable future (Embedded Controllers)”.
