Effect of a high magnetic field on the morphology and magnetic properties of the MnBi compound during the Mn1.08Bi–MnBi phase transformation process
چکیده انگلیسی

Effect of a 10 T high magnetic field on the morphology and magnetic properties of the MnBi compounds during the Mn1.08Bi–MnBi phase transformation has been investigated. Results indicate that the field has split the MnBi crystal along the (0 0 1)-crystal plane during the Mn1.08Bi–MnBi phase transformation process and the split MnBi crystals align and aggregate along the magnetic field direction. Along with the change of the MnBi phase morphology, the magnetic property changes greatly. Indeed, with the alignment and aggregation of the spit MnBi phases, the saturation magnetization Ms and the magnetic susceptibility χ increase, and the coercive field Hc and the remnant magnetization Mr decrease. This implies that a high magnetic field may have caused the magnetic property of the MnBi phase to transform towards soft magnetism. Above results may be attributed to the enhancement of the magnetization and the Mn1.08Bi–MnBi phase transformation in a high magnetic field.
