Description

We investigated the structural and magnetic properties of the as-cast Fe100-(x+y)Si x Nb y (with 9.5x20 and 0.5y12) and Fe78.5Si20Ta1.5 alloys by means of coercivity measurements and zero-field nuclear magnetic resonance (NMR) technique. The NMR spectra of these alloys present broad resonance lines at around 80 and 130 MHz. An increase in the local magnetic stiffness with increasing Nb content was found. These results are discussed based on previously reported results about the microstructure of the same specimen and coercivity measurements
