Abstract

Mössbauer spectra of LaCo12B6 doped with57Fe have been obtained at various temperatures between 4.2 and 293 K. The observed splitting of the subspectrum associated with the 18h site belowTC indicates that the Co sublattice of LaCo2B6 remains ordered in the crystallographic basal plane, with no discernible change in magnetic ordering direction belowTC, contrary to the recent suggestion of a change in magnetic states based on NMR data.
