| Soft magnetic properties of bulk NiFe and NiFeMo alloys consolidated by hot compaction were studied. During annealing the compacts residual stresses diminish by relaxation and soft magnetic properties improve. The lowest coercivity of bulk NiFe and NiFeMo alloys are 11.0 and 11.2 A/m, respectively, while the total losses are 1.81 and 1.42 W/g at f=10 kHz and Bmax=0.2T. |
