dc.description.abstract |
Thermodynamic characteristics of the perovskite-like compound La₂/₃Ba₁/₃MnO₃ exhibiting structural
phase transformation of the martensitic type with characteristic temperature Ts = 200 K have been studied in the
temperature range 2–340 K. Step-like hysteretic temperature behavior of the effective heat capacity has been revealed
at 150–250 K and attributed to the discrete kinetics and a latent heat of the martensitic transformation.
Magnetic subsystem was found exhibiting magnetic glass state below 220 K and temperature hysteresis of the
magnetic susceptibility brightly pronounced in the 40–100 K and 180–230 K regions. The Debye and Einstein
temperatures, Ѳ D = 230 K and Ѳ E = 500 K, respectively, derived from the experimental Debye–Waller factors for
La/Ba, Mn and O sublattices, have been used to refine contributions from the structural and magnetic transformations
to the heat capacity and to reveal thermodynamically nonequilibrium states. |
