Crystal fields and second-order magnetic hyperfine interactions in TmFe2Si2
- 1. Materials Science and Technology Division, Argonne National Laboratory, Argonne, Illinois 60439
Description
We report the measurement of Moessbauer hyperfine spectra of TmFe2Si2 using the 8.4 keV transition in 169Tm. The detailed temperature dependence of the quadrupole interaction has permitted us to evaluate the crystalline electric fields (CEF) acting on Tm atom. The analysis indicates the ground state of Tm to be a singlet state. However, the hyperfine coupling of the 169Tm with the excited CEF states generates a second order magnetic hyperfine interaction which has been observed in our experiment. An account of the spin relaxation of the second-order magnetic hyperfine interaction is presented
