摘要：

Magnetization reversal on recoil curves of a sintered SmCo5 magnet is compared with that for a nanocrystalline SmFeCo alloy prepared by mechanical alloying. Recoil curves were found to be hysteretic and time-dependent in both cases, but magnetic viscosity was observed only for the nanocrystalline SmFeCo alloy. Magnetic interactions were studied via Henkel plots for different initial demagnetized states.
