Structural, electronic, and magnetic entropy contributions of the orbital order-disorder transition in LaMnO(3)
(TAYLOR & FRANCIS LTD, 2011)
Measurements of X-ray diffraction, electrical resistivity, and magnetization are reported across the Jahn-Teller phase transition in LaMnO(3). Using a thermodynamic equation, we obtained the pressure derivative of the ...
On the determination of the magnetic entropy change in materials with first-order transitions

Pressure-induced changes in the magnetic and magnetocaloric properties of RMn(2)Ge(2) (R=Sm,Gd)

Anomalous effect of Si additions upon the paramagnetic-to-antiferromagnetic transition entropy in fcc high-Mn steels
(Elsevier Science SA, 2020-07)
Fe–Mn based alloys with more 12% at. of Mn are usually called High-Mn steels. Several technological properties of High-Mn steels are explained by the presence of the fcc-hcp martensitic transformation. This transition is ...
Entropy Constraints in the Ground State Formation of Magnetically Frustrated Systems: Role of Nernst Postulate in Real Systems
(Springer/Plenum Publisher, 2018-01)
A systematic modification of the entropy trajectory (Sm(T)) is observed at very low temperature in magnetically frustrated systems as a consequence of the constraint (Sm≥ 0) imposed by the Nernst postulate. The lack of ...
