Griffiths-like behavior and magnetocaloric properties of rare-earth silicide TbCoSi.

Novel rare-earth silicide, TbCoSicompound, crystallizes in LuCoGastructure, a distorted substitution variant of thestructure. The compound exhibits a complex magnetic state, with a ferromagnetic transition at 58 K, followed by successive antiferromagnetic transitions at 24 K and 8 K, respectively. Isothermal and magnetic hysteresis studies indicate the prominence of competing antiferro and ferromagnetic interactions in the compound.
