Abstract : The project was initiated to determine if Mossbauer spectrometry can be used to monitor manufacturing processes of permanent magnets made of rare earth-3d transition element compounds. Mossbauer spectra were obtained with absorbers made of powdered NdCo5 alloyed with Fe57. These spectra were obtained at four different temperatures in a range over which a 90 degree rotation of the magnetic axis of NdCo5 is known to occur. The spectra were complex and changed significantly as temperature changed. The number of absorption peaks in each of the spectra indicates that Fe57 may enter three nonequivalent crystal lattice sites in NdCo5. (Author)
