Simulation of magnetization reversal and hysteretic loops of (Nd,Pr)2Fe14B magnets at low temperatures
Original language description
In the present work, the computer simulation of hysteresis loops of (Nd1-xPrx)2Fe14B compounds with different Pr contents was performed for a temperature range of 300-5 K. The simulation results suggest that the alloying of Nd2Fe14B with Pr (1) leads to reducing the negative effect of the spin-reorientation phase transition on the residual magnetization of the compound (Nd1-xPrx)2Fe14B, (2) reduces the slope of the demagnetization curve making the hysteresis loop more rectangular, (3) does not have a noticeable effect on the maximum value of the coercive force, shifting its maximum to lower temperatures as the Pr content increases. Thus, the alloying of Nd2Fe14B-based compositions with Pr can increase the temperature stability of the hysteresis characteristics of permanent magnets and ensures their operation at low temperatures without loss of magnetic properties.
