Magnetic resonance in (FexNi1-x)77B13Si10 reentrant spin glasses
Vertii A. A., Golik A. V. , Takzei G. A. , Tarapov S. I.
A "narrow" resonance peak (of the ESR type), which has not been seen previously, has been observed in the amorphous frustrated alloy (FeJCNi1_^)77B13Sii0 with x= 0.08. This alloy undergoes a reentrant paramagnet-ferromagnet-(spin glass) transition. The peak is seen below the Curie point but above the temperature of the transition to the reentrant-spin-glass phase. A broad magnetic-resonance line is also seen.
