Research on ultramicroscopy detailed by scientists at Mie University
2009 JUN 2 - (NewsRx.com) -- "We measured spin polarization of electrons field-emitted from half-metallic Co2MnSi thin film grown on a W(0 0 1) facet via chromium buffer layer using Mott scattering," investigators in Tsu, Japan report. "For spontaneously magnetized samples, values of polarization at room temperature were observed in a range from 10% to 46% and the polarization direction was < 110 > orientation of substrate tungsten, which agreed with an easy axis of magnetization of bulky Co2MnSi. An enhancement of polarization was observed as a consequence of applying a magnetic field of 350 G perpendicular to the emitter axis after the annealing at 800 K. This result is considered to be caused by improvement in crystallinity of the evaporated film due to annealing," wrote S. Nagai and colleagues, Mie University. The researchers concluded: "Published by Elsevier B.V." Nagai and colleagues published their study in Ultramicroscopy (Spin polarization of field-emitted electrons from half-metallic Co2MnSi thin films grown on a W(001) facet. Ultramicroscopy, 2009;109(5):395-398). For additional information, contact S.
