Short-range order in 1-MnZn alloys as investigated by the NMR of Mn55 nuclei

NMR spectra of Mn55 in five compositions of 1-MnZn alloys have been studied. The various satellite signals observed in all these compositions have been attributed as arising due to occupancy of Mn and Zn atoms in Zn and Mn sites, respectively. The signals have been analyzed using a phenomenological model in which it is assumed that the Mn interaction with the Mn in the first coordination shell is repulsive and that with Zn in the second and third coordination shells is attractive. © 1989 The American Physical Society.
