Abstract :
It is known that the torsion pendulum method provides the possibility of obtaining the anisotropy field strength and the saturation magnetization of magnetically hard materials. This method is extended to obtain the degree of texture. Theoretical calculations are compared with measurements performed on Nd-Fe-B sintered magnets at various temperatures. Error sources are discussed
