초록

The heat capacities of LnCrO<inf>3</inf> (Ln=La, Pr, Nd, Sm, Gd, Dy, Ho, Er and Y) were measured by differential scanning calorimetry (DSC) from 150 to 450 K and also alternating current calorimetry (ACC) from 77 to 280 K. Thermal anomalies due to magnetic transition were observed in all of the heat capacities of LnCrO<inf>3</inf>. The transition temperature and the enthalpy changes depend on rare earth elements. On the other hand, the entropy changes do not depend on ionic radii of the rare earth element. Thermodynamic functions of LnCrO<inf>3</inf> (Ln=Dy, Ho and Y) are calculated above room temperature. © 1997 Elsevier Science S.A.
