Special Issue Information

Dear Colleagues,

With growing concerns about harmful gas emissions and the scarcity of energetic resources, one of the main challenges in the refrigeration industry and the international community is to search for clean cooling technologies with higher thermodynamic efficiency. In this context, solid-state materials that exhibit magnetocaloric, electrocaloric and mechanocaloric effects have recently attracted a worldwide interest, owing to their potential utilization as refrigerants in more compact, efficient, and ecofriendly systems. Such thermal responses can be induced by manipulating the ordering parameters of some specific materials when subjected to variations of magnetic, electric and stress fields, respectively. The implementation of these materials would enable us to fully phase out the hazardous synthetic refrigerants present in conventional cooling systems, such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs), while keeping high thermodynamic performance.

In the present Special Issue, we invite investigators to submit papers that discuss the crystalline structure, physical properties and practical aspects of solid-state caloric materials, including, but are not limited to, bulk forms, single crystals, thin films and nanomaterials.

The potential topics include, but are not limited to:

  • Magnetocaloric materials
  • Electrocaloric materials
  • Mechanocaloric materials
  • Bulk, thin films and nanomaterials
  • Growth of caloric materials
  • Crystalline structure and physical properties
  • Measurement of caloric effects under external excitations
  • Prediction of caloric effects in solid state materials
  • Interplay phenomena in caloric materials
  • Numerical simulation of thermodynamic cycles employing caloric materials
  • Experimental tests in functional caloric devices
  • Mechanical and chemical issues
  • Hysteretic effects in caloric materials
  • Electronic structure
  • Rotating magnetocaloric effect
  • Caloric devices

The effect of different atomic substitutions at Mn sites on the magnetic and magnetocaloric properties in Ni50Mn35Co2Sn13 alloy has been studied in detail. The substitution of Ni or Co for Mn atoms might lower the Mn content at Sn sites, which would reduce the d-d hybridization between Ni 3d eg states and the 3d states of excess Mn atoms at Sn sites, thus leading to the decrease of martensitic transformation temperature TM in Ni51Mn34Co2Sn13 and Ni50Mn34Co3Sn13 alloys. On the other hand, the substitution of Sn for Mn atoms in Ni50Mn34Co2Sn14 would enhance the p-d covalent hybridization between the main group element (Sn) and the transition metal element (Mn or Ni) due to the increase of Sn content, thus also reducing the TM by stabilizing the parent phase. Due to the reduction of TM, a magnetostructural martensitic transition from FM austenite to weak-magnetic martensite is realized in Ni51Mn34Co2Sn13 and Ni50Mn34Co2Sn14, resulting in a large magnetocaloric effect around room temperature. For a low field change of 3 T, the maximum ∆SM reaches as high as 30.9 J/kg K for Ni50Mn34Co2Sn14. A linear dependence of ΔSM upon μ0H has been found in Ni50Mn34Co2Sn14, and the origin of this linear relationship has been discussed by numerical analysis of Maxwell’s relation. Full article

Title: A magnetocaloric booster unit for energy-efficient air-conditioning

Abstract: A novel concept for the application of a magnetocaloric device in energy efficient air conditioners is introduced. In order to evaluate this concept, a test stand has been developed equipped with a cost-effective magnetic field source providing about 1T field change into which different regenerator geometries can be implemented. The powder-in-tube process and tape-casting technology are discussed as promising technologies for shaping magnetocaloric materials into wires or profiled plates that can be readily assembled in the regenerator. Moreover, a model to capture the energy footprint of the magnetocaloric unit in the combined air-conditioner is presented.
