摘要：

Temperature dependencies of magnetic susceptibility and electric resistivity of Co-based metallic glasses (MGs) of the general composition Co((72-x))Me(x)(Si, B)(28) (Me = Fe, Cr, Si:B = 18:10) have been studied up to 950 K. The studied MGs were found to be ferromagnets at the room temperature and their Curie point T(C) ranges within 260-560K depending on the dopant contents. At the temperatures higher than T(C), a wide paramagnetic region exists. The regularities of magnetic moment variation upon Cr doping evidence a formation of antiferromagnetic clusters, which determine the anomalous behavior of resistivity. (C) 2006 Elsevier B. V.
