| Depending on their other constituent elements, Fe-based amorphous materials can exhibit good soft magnetic properties. By determining the directional coefficient b for the relationship of μ0M(μ0H)1/2 according to the best linear fit, it is possible to determine the parameter of spin wave stiffness Dspf. This parameter, amongst others, is related to the distribution of magnetic atoms around the central atom, which is reflected in the value of saturation magnetisation. This work has examined the structure of specially prepared alloy samples and analysed the influence of the spin wave stiffness parameter on the value of saturation magnetisation. Three alloys with different constitutions, based on the Fe matrix, were analysed. |
