Abstract

Strain effects on Tc1 and Tc2 of ErRh4B4 of a primitive tetragonal phase have been investigated by shock-loading experiments for shock-pressures up to 90 GPa. The shock-loading introduces a large random strain into the sample, which is estimated as 0.006 for the sample shocked up to 90 GPa. From the ac susceptibility measurements, Tc1 and Tc2 have been found to decrease and increase with increasing shock-pressure, respectively. The former is considered to be due to crystalline disorder including residual random strain. The latter is understood as a result of residual random strain destroying the tetragonal symmetry.
