摘要：
The soft magnetic properties are reported for newly-developed nanocrystalline Fe72.7Cu1Nb1.8-Mo2Si13B9.5 and Fe73Cu1Nb1.5Mo2Si13B9.5 The high frequency core losses of the new alloys are as follows: P-3/100K=473 kW.m(-3), P-2/200K=750 kW.m(-3), P-2/500K=3400 kW.m(-3), P-0.5/1000K 680 kW.m(-3), which are clearly lower than those of the early-developed Fe-Cu-Nb-Si-B nanocrystalline alloys and the superior power MnZn ferrite H-7c4 The dependences of core loss on frequency and amplitude magnetic flux density have been analysed. The temperature relations of initial susceptibility have been examined for as-quenched and different annealed Fe72.7Cu1Nb1.8Mo2Si13B9.5 alloy acid interpreted by using the phenomenological theory.
