Abstract

0.9. Remarkably, (T-coh)(2) at H = 0 was found to be linearly proportional to T-N. The jump in the magnetic specific heat delta C-m at T-N as a function of T-K/T-N for (Ce1-xLax)Cu2Ge2 follows the theoretical prediction based on the molecular field calculation for the S = 1/2 resonant level model.
