Elastic properties of valence fluctuating CeRhIn

Elastic properties of valence fluctuating CeRhIn

We report the temperature dependence of the elastic modulus and the specific heat of CeRhIn. The elastic modulus softens and takes a minimum around 120 K. The magnetic contribution to the specific heat takes a broad maximum around 130 K. These results suggest a renormalized pseudo-gapped state aroun...

Zusammenfassung:We report the temperature dependence of the elastic modulus and the specific heat of CeRhIn. The elastic modulus softens and takes a minimum around 120 K. The magnetic contribution to the specific heat takes a broad maximum around 130 K. These results suggest a renormalized pseudo-gapped state around the Fermi level E F .
