Abstract :
The suitability of a supermalloy thin film about 1 ¿m thick for use in 1 MHz power equipment was studied. The relationship between the hysteresis loss Wh and the maximum flux density Bm for the approximately 1 ¿m thick films deposited on SiO2 substrate is approximately Wh ¿ Bm1.75. This shows the same tendency as that for the rolled plate, where Wh ¿ Bm1.6, but the hysteresis loss value is one order of magnitude greater. In conventional rolled tape, the hysteresis loss is inversely proportional to tape thickness, but in the case of thin films, Wh obstructs any large-scale reduction in the loss.
