The purpose of this investigation is to determine the magnetic properties of the pseudo-binary alloy system Nd1-xSmxCo5, in particular the variation of the magnetization and magnetocrystalline anisotropy with temperature and composition. The special interest in these variables stems from their quantative relationships to magnetic domain wall characteristics and the relationship of domain walls to RCo5 coercivity, the key parameter in the development of permanent magnets. The experimental method used is based on the measurement of the magnetization parallel and perpendicular to the c-axis of single crystals of the alloy system with a vibrating sample magnetometer. Analysis of the data is made on the basis of the single-ion model of magnetic anisotropy.
