Abstract

The microstructure, transport, and galvanometric properties of Ni₄₈Fe₁₂Cr₄₀ thin films of various thickness, obtained by magnetron sputtering, were studied in the temperature range of 93-293 K. The Ni₄₈Fe₁₂Cr₄₀ film with thickness of 5 nm has been found to be X-ray amorphous and exhibits a negative temperature coefficient of resistance. The observation of anisotropic magnetoresistance, as well as anomalous and planar Hall effect, indicates the presence of ferromagnetic ordering in this sample. The increase of the Ni₄₈Fe₁₂Cr₄₀ film thickness to 8 nm leads to the crystallization and texture formation, which promotes more uniform distribution of Cr atoms in Ni-Fe matrix and suppression of the long-range ferromagnetic order.

Ni48Fe12Cr40薄膜的微观结构、输运及磁流变性能。

在93 ~ 293 K的温度范围内，研究了磁控溅射制备的不同厚度Ni48Fe12Cr40薄膜的微观结构、输运和振镜性能。结果表明，厚度为5 nm的Ni48Fe12Cr40薄膜为x射线非晶态，电阻温度系数为负。各向异性磁阻、反常霍尔效应和平面霍尔效应的观察表明，样品中存在铁磁有序。当Ni48Fe12Cr40薄膜厚度增加到8 nm时，其结晶和织构的形成促进了Cr原子在Ni-Fe基体中的均匀分布，抑制了长程铁磁有序。
