A Study of the Thermodynamic Properties of the La_(0.8)Ag_(0.1)MnO_(3+delta)Solid Solution by the EMF Method with a Solid Electrolyte

摘要

Perovskite manganites of the general formula La_(1-x)A_xMnO_(3+delta)(A is a dopant singly charged cation)are of interest as materials with a colossal magnetore-sistance(CMR)at room temperature[1,2].Among them,La_(1-x)Ag_xMnO_(3+delta)stands out inasmuch as,due to the closeness of its Curie temperature to room temperature,it is promising for treating oncological diseases by the cell hyperthermia method[3]and as a working substance in high-efficiency Freon-free refrigerators[4].
