摘要

Textured MnBi crystals in a Bi matrix are fabricated by quenching at a high temperature (similar to 653 K) in a magnetic field of 10 T. Microstructure observations reveal that MnBi grains are aligned along their c-axis. Magnetization measurements show a pronounced magnetic anisotropy in directions normal and parallel to the fabrication field resulting from the alignment. MnBi crystals display spin-disorder behaviors in ac magnetization, which may emerge due to the quenching processing.
