EXPLORATION OF NEW MULTIFUNCTIONAL MAGNETIC MATERIALS BASED ON A VARIETY OF HEUSLER ALLOYS AND RARE-EARTH COMPOUNDS
Magnetic, magnetocaloric, magnetotransport and magnetoelastic properties of Ni-Mn-X (X = In, and Ga) Heusler alloys and La-Fe-Si based rare earth compounds have been synthesized and investigated by x-ray diffraction, magnetization, strain, and electrical resistivity measurements. The phase …

Ab initio based Monte Carlo model of phase transformations in ferromagnetic shape memory alloys
… the degree to which they will exhibit the magnetocaloric effect (MCE), which is a promising alternative to conventional refrigeration mechanisms. Our framework consists of a combination of ab-initio simulations and Monte Carlo models which allow an alloy to be examined across its phase …

Optimization of Materials for Magnetic Refrigeration and Thermomagnetic Power Generation
<p>The magnetocaloric effect, by which a magnetic material experiences a change in temperature due to an applied magnetic field, can be used for refrigeration. The corollary to the magnetocaloric effect -- known as the pyromagnetic effect -- is the phenomenon by which a magnetic material …

EXPLORATION OF NEW MAGNETOCALORIC AND MULTIFUNCTIONAL MAGNETIC MATERIALS
… value is comparable to those of well-known giant magnetocaloric materials, such as Gd5Si2Ge2, MnFeP0.45As0.55, and Ni50Mn37Sn13. The values of the latent heat (L = 6.6 J/g) and corresponding total entropy changes (∆ST = 35 J/kg K) have been evaluated for the MST using DSC measurements. Large …

Investigation of the magnetic and magnetocaloric properties of complex lanthanide oxides
… this dissertation, the structural, magnetic and magnetocaloric properties of three families of lanthanide oxides have been studied with the dual aims of investigating the magnetic behaviour and identifying promising magnetic refrigerants for cooling to temperatures currently accessible using …

Tuning Strong Correlated Properties in EuTiO3 Thin Films Grown by Pulsed Laser Deposition
… there is an increasing interest in exploring the magnetocaloric effect (MCE) in ETO-based bulk materials. First, systematic studies for optimizing the growth condition for ETO-based self-assembled vertically alligned nanocomposite (VAN) thin films were carried out. We carried out investigations …

Caloric effects in ferroic materials
… systems that do not use harmful fluids. Magnetocaloric, electrocaloric and mechanocaloric materials have been studied independently as potential replacement of these fluids refrigerants but each has its own limitations. More recently, multicaloric materials that respond to multiple fields …
