Irreversible Heat Flow Across Phase Boundaries in Phase-Separated Manganites

14 Jul 2020 Lima-Sharma A. L. Sharma P. A. Boekema C.

We have investigated the change in entropy with direct measurements of heat flow as a function of magnetic field at fixed temperatures across the entire phase diagram of the phase-separated (PS) compound La$_{0.25}$Pr$_{0.375}$Ca$_{0.375}$MnO$_3$ (LPCMO). At this composition, the compound shows competing charge-ordered/antiferromagnetic (CO/AF) ground states... (read more)
