NMR study of magnetic properties in SmRu4P12

31P-NMR and studies of filled skutterudite compounds RRu4P12 (R: Sm, Gd)

“…With increasing field, the line shape below T MI indicates a complicated magnetic structure which is different from a simple AFM one in SmOs 4 P 12 [8]. By the analysis of the Knight shift obtained from the spectra, the hyperfine coupling constant of H hf ' 2:7 kOe=m B was estimated, which is consistent with a previous result [7]. Fig.…”

“…The line width of the spectrum rapidly increases below T MI but not below T N . The line shape below T MI in low fields shows a triangle-type powder pattern which is often observed in SDW systems [7]. With increasing field, the line shape below T MI indicates a complicated magnetic structure which is different from a simple AFM one in SmOs 4 P 12 [8].…”
