【摘要】 <正> 近年来,对稀土和铁族(Fe、Co、Ni、Mn)所组成的非晶态合金性能的研究,引起了人们很大的兴趣,这不仅因为这些合金的性能和相应的晶态合金相比有很大的差别,而且它们还具有潜在的应用价值。对非晶态稀土磁性合金的电子输运特性,也有一些报道,如Fert更多还原

【Abstract】 We report here the preliminary measurement of the temperature dependence of resistivity in sputtered amorphous Gd-Co films within the temperature range of 4.2—300 K. Interesting behaviours of temperature dependence have been observed in the uniaxial perpendicular magnetic anisotropic films (with a predominance of Gd-Co pairs) and inplane magnetic anisotropic films respectively. With regard to the former films, the resistivity exhibits a minimum at about 50 K and from 4.2 K to 25 K, the resistivity ρ is proportional to —In T; but, with regard to the latter films, from 300 K down to 7 K, the resistivity ρ is proportional to —In T and below 7 K, the resistivity shows a rather abrupt drop.更多还原
