Magnetic viscosity in Nd-Fe-B sintered magnets

Magnetic viscosity in Nd-Fe-B sintered magnets was measured at different fields between 4.2 and 300 K. At a given temperature, the viscosity S( H) and the irreversible susceptibility χ irr are found to be proportional. The temperature dependence of the coefficient S v = S/ χ irr is deduced and an ex...
