Abstract:
Heat capacity measurements of CeCu 2.05Si 2 have been carried out at
temperatures down to 0.1 K under magnetic field up to 13 T. The heat
capacity divided by temperature C/T has revealed as a characteristic
feature that the peak of C/T shifts down to around 0.5 K with increasing
field up to 7 T, whereafter it shifts up again to around 0.6 K at 13 T.
In the first case, a peak appears around the phase boundary (labeled A)
first found in NMR and magnetoresistance. Most remarkably, in the latter
case, the peak coincides with the new phase boundary (labeled B)
identified recently by elastic constant and thermal expansion
measurements.
