Specific heat of a quasidegenerate magnetic semiconductor

An investigation was made of Eu/sub 1-x/Gd/sub x/O solid solutions exhibiting quasimetallic conduction. The temperature dependences of the specific heat and magnetocaloric effect were determined for two samples with xapprox. =0.01 and 0.035. Two Curie points were observed for the latter sample. Possible reasons for this behavior were considered.
