Abstract

The intrinsic magnetism of Gd2Fe2Si2C has been investigated using magnetization and specific heat measurements. Gd2Fe2Si2C orders magnetically below 58 K, consistent with the de Gennes scaling observed for the remaining (heavy-R) R2Fe2Si2C compounds.A second magnetic event at ∼38 K is also observed in the susceptibility and specific heat data which might signal a spin–reorientation transition. Field dependent magnetometry suggests that the magnetic structure of this compound is quite complex.
