Ratio between the relaxation times τ of the Fe and Ni sublattices in Py after the application of a heat pulse of temperature Tpulse for a range of values of the ratio of intrinsic damping parameters λFe/λFe. Black lines represent λFe/λNi values where the ratio between relaxation times τNi and τFe is constant with the value given by the label.
