The role of interfaces on the magnetic behavior of granular CuFeCo alloys.
In: Physica Status Solidi A : Applications and Materials Science, 202 (10), pp. 2008-2012. WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, [Article]
Abstract
Granular thin films of face centered tetragonal (fct) FeCo-clusters in a γ-CuCo matrix show a giant magneto resistance effect. Cu100–x(Fe50Co50)x samples with 63 ≤ x ≤ 88 were examined using Mössbauer Spectroscopy, electron microscopy, Magnetoresistance, SQUID and Rutherford Backscattering Spectroscopy. In ultrafine particles with fct-FeCo imbedded in a CuCo matrix the giant magneto resistance effect is strongly correlated to the ratio of interface/bulk. The magnetic interfaces form an additional scattering centere for the electrons which causes an increase of the GMR effect.
