Abstract
The crystal and the magnetic properties of the N50 permanent magnet, which is widely used in industrial applications, have been studied by using x-ray diffractometer (XRD), vibrating sample magnetometer (VSM), and Mossbauer spectrometer. The crystal structure was determined to be tetragonal with a Nd-Fe-B structure. Based on the M-T curves, the values of spin reorientation temperature (T SR ) and Curie temperature (T C ) were found to be 130 and 600 K, respectively. The Mossbauer spectra of N50 showed abrupt changes in the magnetic hyperfine field (H hf ) and the electric quadrupole shift (E Q ) at temperatures around 130 K, indicating a spin reorientation (T SR ). From the Mossbauer absorption area as a function of the square of the temperature for the N50 permanent magnet, the Debye temperature (Θ D ) was found to be Θ D = 414.7 K.
