Abstract
Series samples MnBi1-xGdx (x = 0, 0.04, 0.08, 0.12, and 0.16) were prepared and studied the structure and magnetic properties. The Rietveld refinement results showed that the low-temperature phase MnBi content in these samples is above 78% and the doped atoms occupied the position of Bi in the MnBi crystal structure. The Debye temperature is founding to decrease with increasing doping. The Curie temperature, paramagnetic to ferromagnetic transition temperature, thermal hysteresis, saturation magnetization, and coercive force of the samples change significantly with increasing doping content. Within a temperature range of 300–500 K, a positive coercivity temperature coefficient β existed. This work helps MnBi-Gd as a candidate for high-temperature magnetic material applications and contributes to the development of tailoring magnetic properties.
