Abstract

The impurity heat capacity of solid 3 He–4 He mixtures is theoretically investigated both below and above phase separation temperature T s . It is shown that at T > T s the temperature behavior of the heat capacity is completely defined by correlation effects in the impuriton subsystem. The proposed theory is in good agreement with experimental data.
