“…It is highly desirable to develop novel cooling technologies to replace the current vapor‐compression technology, which has low energy efficiency and uses environmentally harmful refrigerants. Magnetocaloric refrigeration based on the magnetocaloric (MC) effect has been explored as an alternative after the successful development of magnetic refrigerator prototypes . However, MC refrigeration requires a large‐volume permanent magnet or a high electric current to generate a large magnetic field change.…”

Extraordinarily Large Electrocaloric Strength of Metal‐Free Perovskites

The availability of materials with high electrocaloric (EC) strengths is critical to enabling EC refrigeration in practical applications. Although large EC entropy changes, ΔSEC, and temperature changes, ΔTEC, have been achieved in traditional thin‐film ceramics and polymer ferroelectrics, they require the application of very high electric fields and thus their EC strengths ΔSEC/ΔE and ΔTEC/ΔE are too low for practical applications. Here, a fundamental thermodynamic description is developed, and extraordinarily large EC strengths of a metal‐free perovskite ferroelectric [MDABCO](NH4)I3 (MDABCO) are predicted. The predicted EC strengths: isothermal ΔSEC/ΔE and adiabatic ΔTEC/ΔE for MDABCO are 18 J m kg−1 K−1 MV−1 and 8.06 K m MV−1, respectively, more than three times the largest reported values in BaTiO3 single crystals. These predictions strongly suggest the metal‐free ferroelectric family of materials as the best candidates among existing materials for EC applications. The present work not only presents a general approach to developing thermodynamic potential energy functions for ferroelectric materials but also suggests a family of candidate materials with potentially extremely high EC performance.

“…The most recent and most comprehensive review of magnetocaloric materials can be found in the work of Franco et al Another very important article on the material selection criteria was recently published by Gottschall et al The latest review of manganese‐based magnetocaloric materials was presented by Chaudhary et al, while another interesting publication was authored by Lyubina, who reviewed magnetocaloric materials with an adiabatic temperature change rate of higher than 2 K T –1 . Some older reviews are also available in the literature …”

“…Another important issue worthy of future research is the use of nanoengineering methods to achieve improvements such as broadening of the magnetocaloric effect and strengthening its intensity. This may not be effective for FOMT materials but would be a useful tool for tailoring manganites . Nanostructuring of Gd‐Ti into multilayers has been used to enhance the magnetic field responsiveness, and this may be also interesting for other types of materials .…”

“…Several researchers have concluded that caloric (ferroic) refrigeration and heat‐pumping technologies, which are still in the research and development phase, are the most important option for the future . These solid‐state technologies variously utilize magnetocaloric, electrocaloric, and mechanocaloric effects. A material that exhibits more than one of these effects is described as a multicaloric (multiferroic) material with multicaloric effects .…”

The need for energy‐efficient and environmentally friendly refrigeration, heat pumping, air conditioning, and thermal energy harvesting systems is currently more urgent than ever. Magnetocaloric energy conversion is among the best available alternatives for achieving these technological goals and has been the subject of substantial basic and applied research over the last two decades. The subject is strongly interdisciplinary, requiring proper understanding and efficient integration of knowledge in different specialized fields. This review article presents a historical and up‐to‐date account of the energy‐related applications of magnetocaloric materials and information about their processing and magnetic fields, thermodynamics, heat transfer, and other relevant characteristics. The article also discusses the conceptual design of magnetocaloric refrigeration and power generation systems and some guidelines for future research in the field.

“…There are a large number of alloys prepared in this class of materials, evidenced by the number of publications appearing in ISI Web of Science each year [26]. Additionally, review articles have been published on MSM/MMSM materials [13] and magnetocaloric materials [2,20,27]. Particular to MCE, research is also being carried out on using materials with reduced dimensions, such as thin films, ribbons and microwires [28].…”

Ferromagnetic Shape Memory Heusler Materials: Synthesis, Microstructure Characterization and Magnetostructural Properties

et al. 2018

View full text Add to dashboard Cite

An overview of the processing, characterization and magnetostructural properties of ferromagnetic NiMnX (X = group IIIA–VA elements) Heusler alloys is presented. This type of alloy is multiferroic—exhibits more than one ferroic property—and is hence multifunctional. Examples of how different synthesis procedures influence the magnetostructural characteristics of these alloys are shown. Significant microstructural factors, such as the crystal structure, atomic ordering, volume of unit cell, grain size and others, which have a bearing on the properties, have been reviewed. An overriding factor is the composition which, through its tuning, affects the martensitic and magnetic transitions, the transformation temperatures, microstructures and, consequently, the magnetostructural effects.
