Article Synopsis
  • * Research highlights the large barocaloric effect (BCE) in MnPt, showing a significant temperature change strength of 9.77 K per 100 MPa, driven by low pressure and geometrical frustration.
  • * The study reveals that geometrical frustration enhances BCE by inducing strong spin fluctuations and magnetic moment changes, leading to greater sensitivity in magnetic phase transitions and advancing barocaloric refrigeration research.

Article Synopsis
  • * A new strategy enhances the thermal conductivity and machinability of negative thermal expansion alloy (Zr,Nb)Fe by incorporating eutectic copper networks, resulting in over 200% increased thermal conductivity and improved mechanical strength.
  • * The addition of copper modifies the (Zr,Nb)Fe composition, leading to better thermal management and stability across a wider temperature range, while also improving bonding and stress handling capabilities of the alloy.

Magnetic refrigeration technology can achieve higher energy efficiency based on the magnetocaloric effect (MCE). However, the practical application of MCE materials is hindered by their poor mechanical properties, making them challenging to process into devices. Conventional strengthening strategies usually lead to a trade-off with refrigeration capacity reduction.
