Abstract :
Microwave permeability spectra of ferromagnetic glass-coated microwires at room temperature have already been studied. Using a new setup that we have recently developed, permeability spectra of ferromagnetic microwire at various temperatures are presented. CoFeSiB soft ferromagnetic microwires are studied from 150 K to 450 K, showing large changes in their permeabilities between 30 MHz and 3 GHz.
