Abstract
We present an experimental investigation of the temperature and magnetic field dependence of the elastic constants in the two stannide compounds Yb 3 Rh 4 Sn 13 and Ca 3 Rh 4 Sn 13 . We find a small elastic softening of the c44 mode of ca. 2% in the normal state. The temperature dependence of the various elastic modes are quite anomalous in the superconducting state. A comparison of our results is given with corresponding results of CeRu 2 , an amorphous superconductor and other amorphous materials.
