Anisotropic magnetocaloric effect in all-ferromagnetic (La0.7Sr0.3MnO3/SrRuO3) superlattices

Cryogenic magnetocaloric effect in a ferromagnetic molecular dimer.

Over the last few years, great interest has emerged in the synthesis and magnetothermal studies of polymetallic molecular clusters based on paramagnetic ions, often referred to as molecular nanomagnets, in view of their potential application as lowtemperature magnetic refrigerants.[1,2] What makes them promising is that their cryogenic magnetocaloric effect (MCE) can be considerably larger than...

Crystallography, anisotropic metamagnetism, and magnetocaloric effect in Tb5Si2.2Ge1.8

The metamagnetic-like transitions and giant magnetocaloric effect were observed with the magnetic field applied parallel to the aand c axes, but not the b axis in a Tb5Si2.2Ge1.8 single crystal. The in situ x-ray powder diffraction study indicates that these metamagnetic-like transitions are coupled to crystallographic phase transformations occurring via strong magnetoelastic interactions. The ...

Anisotropic Magnetocaloric Effect and Magnetic Order in Antiferromagnetic Gd2InGe2

We investigated the transport, thermal and magnetic properties of antiferromagnetic (TN = 45 K) Gd2InGe2. Magnetization measurements under applied magnetic field, oriented along different crystallographic directions, were used to extract the anisotropic magnetocaloric effect. We also measured magnetization under pulsed field up to 45 T. From the analysis of the electrical transport and magnetiz...

Magnetocaloric properties of Co/Cr superlattices

Nanostructured materials for refrigeration applications are experimentally realized by molecular beam epitaxial growth of Co/Cr superlattices using mean-field theoretical concepts as guiding principles. Magnetocaloric properties are deduced from measurements of the temperature and field dependence of the magnetization of our samples. More generally, the potential of artificial antiferromagnets ...
