Thermodynamics of multicaloric effects in multiferroic materials; application to metamagnetic shape memory alloys and ferrotoroidics [PDF]
We develop a general thermodynamic framework to investigate multicaloric effects in multiferroic materials. This is applied to the study of both magnetostructural and magnetoelectric multiferroics.

Frustrated magnetism and caloric effects in Mn-based antiperovskite Nitrides : Ab Initio theory [PDF]
We model changes of magnetic ordering in Mn-antiperovskite nitrides driven by biaxial lattice strain at zero and at finite temperature. We employ a non-collinear spin-polarised density functional theory to compare the response of the geometrically ...

Multiferroic and related hysteretic behavior in ferromagnetic shape memory alloys [PDF]
We combine a Ginzburg–Landau model for a ferroelastic transition with the theory of micromagnetism to study the magnetostructural behavior leading to multicaloric effects in ferromagnetic shape memory alloys.

Elastocaloric switching effect induced by reentrant martensitic transformation [PDF]
Vapor compression technologies widely used for refrigeration, heating, and air-conditioning have consumed a large fraction of global energy. Efforts have been made to improve the efficiency to save the energy, and to search for new refrigerants to take the place of the ones with high global warming potentials.

Temperature contour maps at the strain-induced martensitic transition of a Cu–Zn–Al shape-memory single crystal [PDF]
We study temperature changes at the reverse strain-induced martensitic transformation in a Cu–Zn–Al single crystal. Infrared thermal imaging reveals a markedly inhomogeneous temperature distribution.

Ultrahigh cyclability of a large elastocaloric effect in multiferroic phase-transforming materials
Multiferroic phase-transforming alloys demonstrate intriguing multicaloric effects, but they are intrinsically brittle and their elastocaloric effect shows poor cyclability, which remains a major challenge for exploiting more efficient multicaloric ...

Colossal magnetocaloric effect in magneto-auxetic systems [PDF]
We show that a mechanically driven magnetocaloric effect (MCE) in magneto-auxetic systems (MASs) in the vicinity of room temperature is possible and the effect can be colossal.

In this work, we have studied the elastocaloric effect in directionally solidified Co51.6V31.4Ga17 alloys with a strong [001] preferred orientation. The entropy change for thermal-induced martensitic transformation is determined as 19.6 J kg−1 K−1.
