The basic error leading to this belief is pointed out explicitly and the various methods of calculation used are viewed in a unified way based on the Lorentzian lineshape of ferromagnetic resonance spectra. A general torque formula for {\\alpha} is proposed as a good starting-point for treating inhomogeneous materials such as alloys, compounds and layered structures.
