We have extended the calculations of the hyperfine field and nuclear quadrupole coupling assuming the principal axis of the electric field gradient (EFG) to be parallel to the hyperfine field ( H hf ), to the case where this parallelism does not exist, to obtain a more adequate reproduction of the Mössbauer spectra of Cd 1— x Fe x Cr 2 S 4 ( x = 0.01, 0.02) and Mn 0.99 Fe 0.01 Cr 2 S 4 . The parameters found are noticeably different from those reported in the literature.
