| Abstract: | The influence of high magnetic field on the morphology of MnBi phase was investigated. It was found that under the magnetic field of 10T and at a certain range of temperature, the MnBi transformed from the paramagnetic phase into the ferromagnetic phase and the MnBi crystal was split into many small crystals which oriented and aggregated along the magnetic field direction. The effects of magnetic field on phase transformation temperature and the morphology of MnBi phase were analyzed from the viewpoint of magnetic field induced strain. |
