Abstract
Abstract
In this work the magnetic properties of (Nd,Pr)2Fe14B alloys have been investigated in a wide range of temperatures (4.2 – 700 K) and magnetic fields (up to 14 T). The features of the structure were studied using two methods: SEM and AFM/MFM. Magnetic phase transition diagram was constructed. In the region of magnetic phase transitions (Curie and spin- reorientation transition temperatures) the value of the magnetocaloric effect was determined as an entropy change. The constancy of the magnetocaloric effect value for (Nd,Pr)2Fe14B alloys has been established.
