Improving the validity of hyperfine field distributions from magnetic alloys Part II: Polarized source and spin texture
It has been shown in Part I of this work that 57Fe Mössbauer spectra for the case of mixed electric and magnetic interactions can be calculated with much higher accuracy by using higher order perturbation theory. This is extended for the case of polarized radiation in order to treat cases of magnetic texture in more detail. It is shown that, in this case, the line intensities can be expressed as functions of the magnetic texture including the perturbation of the electric quadrupole interaction. As in Part I, the case of an isotropic electric quadrupole texture is considered.
