Heat capacity measurements on FeAs-based compounds: a thermodynamic probe of electronic and magnetic states
We report heat capacity measurements of the pnictide materials SmFeAsO1−xFx , NdFeAsO, LaFeAsO1−xFx and LiFeAs. For SmFeAsO1−xFx ,with x close to 0.1, we use 3He measurements to demonstrate a transfer of entropy from the peak at TN to a previously unidentified ~ 2K feature, which grows with increasi...
