Substitution Effect on Magnetic and Electrical Properties of Half-Heusler Alloy Ni_(1-x)Co_xMn_(1-y)Fe_ySb

摘要

We have studied the effects of Co and Fe doping on the magnetic and electrical properties of half-Heusler compound NiMnSb. The alloys were prepared by arc-melting method in the presence of Argon gas. The powder X-ray diffraction of the each alloy was performed in air at room temperature. The magnetic and electrical properties were performed in the temperature range 2-400 K and in magnetic field up to 1 T.
