Description

We have carried out 55Mn and 149Sm NMR measurements on SmMn2-xFexGe2 (0.05 ≤ x ≤ 0.6) at 4.2 K in order to elucidate the Fe substitution effect on the magnetic properties of SmMn2-xFexGe2. The NMR signals of Mn have been observed in the frequency range 180 - 210 MHz. The resonance frequency plotted against the Fe concentration shows an abrupt change between x = 0.3 and 0.4. This discontinuity suggests that the magnetic structure changes around x = 0.35 in the low temperature range where Sm and Mn sublattices order magnetically.
