Research demonstrates increased Curie temperature and coercive force in MnZnSb solutions, suggesting thermal treatment enhances magnetic properties.
The paper studies the effect of high-temperature treatment on structural and magnetic properties of the system MnZn 1- x Cr x Sb (0 ≤ x ≤ 0.20) solid solutions obtained by solid-phase reactions with subsequent quenching. It was shown all solid solutions have a tetragonal crystal structure with P 4/ nmm space group, which is preserved under high-temperature treatment. The temperatures of the magnetic phase transition increase with grow substitution concentration. High-temperature treatment of the initial MnZnSb compound leads to increasing of Curie temperature and coercive force. The effect of substitution concentration on the coercive force and magnetization value has been discovered.
