TL;DR: The magnetocaloric effect (MCE) in paramagnetic materials has been widely used for attaining very low temperatures by applying a magnetic field isothermally and removing it adiabatically as discussed by the authors.

TL;DR: In this paper, the structural and magnetic transformations in the Heusler-based system are studied by x-ray diffraction, optical microscopy, differential scanning calorimetry, and magnetization.

TL;DR: In this paper, the magnetic and structural transformations in the Heusler-based system were studied in the composition range $0.05, 0.16, and 0.25, respectively, and the magnetic coupling in both austenitic and martensitic states is ferromagnetic.

TL;DR: The magnetic superelasticity and the inverse magnetocaloric effect in Ni-Mn-In and their association with the first-order structural transition are studied by magnetization, strain, and neutron-diffraction studies under magnetic field as mentioned in this paper.

TL;DR: In this article, the authors have modelled the phase diagram of magnetic shape memory alloys of the Heusler type by using the phenomenological Ginzburg-Landau theory and found that the driving force for structural transformations is considerably enhanced by the extremely low lying optical modes of Ni, which interfere with the acoustical modes enhancing phonon softening of the TA2 mode.
