Magnetic Phase Transitions and Magnetic Structures in Mn-based Compounds

The growing demand for energy highlights the need for developing more efficient and environmentally friendly technologies. Magnetic cooling based on the magnetocaloric effect is a promising alternative for compressor-based refrigeration. Among various magnetocaloric materials, Mn-based alloys appear especially attractive due to their low cost,...

Tuning Giant Magnetocaloric Materials: A Study of (Mn,Fe)2(P,Si) and NiCoMnTi Heusler Compounds

Solid‐state caloric effects as intrinsic responses from different physical external stimuli (magnetic‐, uniaxial stress‐, pressure‐ and electronic‐ fields) have been evaluated near magnetic phase transformations. In the last decades the magnetically driven caloric changes in various magnetocaloric materials (MCMs) have been exploited extensively...

Design of efficient magnetocaloric materials for energy conversion

The magnetocaloric effect (MCE) is a magneto-thermodynamic phenomenon in which a temperature change of a material is caused by exposing the material to a changing magnetic field under adiabatic conditions. There are two main applications based on the MCE. One application is magnetic refrigeration, which can expel heat in a magnetic field cycle....

First-order phase transitions and giant magnetocaloric effect

Modern society relies on cooling technology for food safety, comfort and medical applications. The solid-state cooling technology known as magnetic refrigeration is one of the most promising techniques to replace the current vapor-compression cooling technology. To date, the search for suitable materials with a large magnetocaloric effect (MCE)...
