Universal scaling of latent heat of orbital order-disorder transition with average R-site ion size in perovskite RMnO3 systems
Parthasarathi Mondal, Dipten Bhattacharya
The latent heat (L) of orbital order-disorder transition in single-valent perovskite manganite series La(1-x)R(x)MnO3 (R = Pr, Nd, Gd; x = 0.0-1.0) decreases with the decrease in a…
Particle-size dependence of orbital order-disorder transition in LaMnO3
Nandini Das, Parthasarathi Mondal, Dipten Bhattacharya
The latent heat (L) associated with the orbital order-disorder transition at T_JT is found to depend significantly on the average particle size (d) of LaMnO3. It rises slowly with…
Dielectric anomaly at the orbital order-disorder transition in LaMnO_(3+delta)
Parthasarathi Mondal, Dipten Bhattacharya, Pranab Choudhury
We report a novel dielectric anomaly around the Jahn-Teller orbital order-disorder transition temperature T_JT in LaMnO_(3+delta). The transition has been characterized by resistiv…
Particle size dependence of magnetization and phase transition near T_N in multiferroic BiFeO3
R. Mazumder, S. Ghosh, P. Mondal +8
We report results of a comprehensive study of the phase transition at T_N (~643 K) as a function of particle size in multiferroic BiFeO3 system. We employed electrical, thermal, an…
