Suppose I have FMR line shapes (dP/dH) at different temperatures for a particular frequency, say 10 GHz. If the line shape contains both absorptive and dispersive components, we can fit the line shape with symmetric and antisymmetric Lorentzian functions to obtain Hres and line width.
Is there a way to estimate the temperature dependence of dc electrical resistivity of the sample from the FMR line shapes (or from the extracted line widths)? Since the permeability depends on DC resistivity, FMR line shape should also depend. Thank you in advance for your help.
FMR signal also relies upon the skin depth of your sample. Generally higher the penetration of the microwaves inside your sample, higher will be the FMR absorption. So one can try to estimate the resistivity of sample by observing the change in the amplitude of FMR signal. Provided you should have a temperature dependent resistivity and skin depth profile of our sample.
