✦ Synopsis

The specific heat of po'wdered CuCI2.2H20 has been measured from 1.5 to 5.0°K and from 14 to 20°K. A }~-shaped peak is found in the Cp versus T-curve having its maximum at 4.31°K, the N6el temperature at which a transition occurs from the anti-ferromagnetic to the paramagnetic state. The total entropy change associated with this process is found to b2 5.45 joules/deg mol, approximately one-third of this being gained above the N6el point. Other characteristics of the anomalous peak are digCUSsed.

New accurate measurements of the specific heat of Gd2(SO4)3.8H20 in zero magnetic field between 1.0 and 3.0°K are presented, and used to obtain information on the electronic part of the specific heat. The experimental results combined with theoretical considerations provide good evidence, that in a
