Abstract

Electrical resistivity of Co₄₈Fe₂₅Si₄B₁₉Nb₄ amorphous alloy and with small additions of rare-earth metals (= Nd, Sm, Tb, Yb) was studied using the AC four-probe method. It was found that these alloys have a specific behavior of electrical resistivity after crystallization-temperature dependences of resistivity at cooling are non-linear and can be fitted as ln R ~ T^−1/4.

非晶态和结晶态 Co-Fe-Si-B-Nb-R 合金的异常电阻率

使用交流四探针法研究了 Co48Fe25Si4B19Nb4 非晶合金和少量添加稀土金属（= Nd、Sm、Tb、Yb）的电阻率。研究发现，这些合金在结晶后具有特定的电阻率特性--冷却时的电阻率与温度的关系是非线性的，可拟合为 ln R ~ T-1/4。

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
