The intrinsic magnetism of Gd 2 Fe 2 Si 2 C has been investigated using magnetization and specific heat measurements. Gd 2 Fe 2 Si 2 C orders magnetically below 58 K, consistent with the de Gennes scaling observed for the remaining (heavy‐R) R 2 Fe 2 Si 2 C 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.
