Acoustic emission across the magnetostructural transition of the giant magnetocaloric Gd5Si2Ge2 compound
Francisco-Jose Perez-Reche, Felix Casanova, Eduard Vives +5
We report on the existence of acoustic emission during the paramagnetic-monoclinic to ferromagnetic-orthorhombic magnetostructural phase transition in the giant magnetocaloric Gd5S…
Zero Temperature Hysteresis in Random Field Ising Model on Bethe Lattices: approach to mean field behavior with increasing coordination number z
Xavier Illa, Prabodh Shukla, Eduard Vives
We consider the analytic solution of the zero temperature hysteresis in the random field Ising model on a Bethe lattice of coordination number , and study how it approaches the…
Equivalence of nonadditive entropies and nonadditive energies in long range interacting systems under macroscopic equilibrium
Ramandeep S. Johal, Antoni Planes, Eduard Vives
We discuss that the thermodynamics of composite systems with non-additive entropies and additive energies can be equivalently derived considering additive entropies and non-additiv…
