Electrical and Magnetic Properties of Nd2Fe14B Magnet in Demagnetized and Magnetized States at Low Temperatures

Below room temperature the spin reorientation phase transition was observed for Nd2Fe14B magnet with Tsr ∼ 135 K. Spin reorientation refers to a change in the preferred direction of the M magnetization. The Nd2Fe14B magnet changes from a uniaxial or easy-axis material at TTsr to an easy-cone material at T
