The influence of 3d-impurities on magnetic and transport properties of CoSiB metallic glasses
Source abstract
Abstract
Abstract 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 260–560 K 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.
