Abstract
Comprehensive studies of the thermophysical properties (thermal conductivity, thermal diffusivity, heat capacity, thermal expansion coefficient) of solid solutions of the Bi0.9M0.1FeO3 (M = La, Pr, Nd, Sm) multiferroics have been carried out within the temperature range of 300–800 K. Anomalies of the thermophysical properties caused by phase transitions are observed within the Néel temperature domain (640–650 K). Formulas are proposed for the calculation of the studied thermophysical properties within the domains of the structural phase transitions, and a clear correlation is established for the dependences of the thermophysical properties within the domain of the structural phase transitions.
