Abstract
- The magnetic energy losses and their frequency dependence are investigated in the TbDyFe/epoxy giant magnetostrictive composites. The value of total loss is extremely low in the composite which is only 3.7% of the monolithic TbDyFe alloy at high frequency of 100 kHz under the peak magnetic induction of 10 mT. With the measured loss values, fitting formulas are suggested to deeply study the contributions of hysteresis loss and eddy current loss to the total loss. The dominant loss is hysteresis loss for the composite and eddy current loss for the monolithic TbDyFe alloy. [ABSTRACT FROM AUTHOR]
