Abstract
The effect of the rf modulation of the Mössbauer gamma radiation (rf sidebands) and the effect of the fast relaxation of the magnetic hyperfine field induced by the rf field (rf collapse) are described. The coexistence and separation of these effects is discussed. The rf collapse of the magnetic hyperfine structure allows a direct observation of the quadrupole interaction in ferromagnetic amorphous metals providing the method for studying the short range order. Examples of FeSiB, FeNiSiB, FeCoSiB and FeB are discussed with respect to structural models. The effect of radiofrequency enhanced crystallization of amorphous metals and its relation to rf sidebands is demonstrated.
