TEMPERATURE DEPENDENCE OF COERCIVITYFOR SOME INTERMETALLIC FERROMAGNETSAT LOW TEMPERATURE
Chen Bin (Department of Physies)
Starting from the dynamic equation of motion of a moving Bloch Wall system.we obtain the exact eigenlevels of the quantized system.and also give an equation for determining the temperature dependence of the coercive field at low temperature for small in-termetallic ferromagnetic particles. It is found that at much low temperature the coer-civies of the materials are constants. which is at least qualitatively consistent with the experiments.
