TechConnect World

If you are going to next week’s TechConnect World Innovation Conference & Expo in National Harbor, MD (Washington, D.C.), please consider attending our poster session, “First-Order-Reversal-Curve Analysis of Nanoscale Magnetic Materials,” which will be presented by Brad Dodrill, Lake Shore Senior Scientist and VP of Sales. The presentation will be among those held Wednesday, June 18, starting at 4 p.m. in the Potomac Registration Hall of the Gaylord National Convention Center.

This session will be based on a paper that Dodrill co-authored with Dr. Leonard Spinu of the University of New Orleans. In the paper (which will be made available on our website after the conference & expo), Dodrill and Spinu discuss the synthesis of magnetic nanowire arrays and the first-order-reversal-curve (FORC) measurement and analysis method and present results for an array of nickel (Ni) nanowires.

FORC measurements are particularly useful because it is not possible to obtain information related to interactions or coercivity distributions by measuring hysteresis loops alone. In this paper, FORCs were used to determine the distribution of switching and interaction fields in a periodic array of magnetic nanowires. Lake Shore MicroMag™ VSM/AGMs are ideal for performing FORC measurements owing to their measurement speed because a typical series of FORCs can contain thousands of data points.

For additional information, be sure to read this earlier written application note on the use of FORC measurements. Or please feel free to contact Lake Shore.
