  • Here, the authors report parametric down-conversion of X-rays into long wavelength radiation in gallium arsenide and lithium niobate crystals, with efficiencies about 4 orders of magnitude stronger than the efficiencies measured in any material studied previously. They explore the lack of inversion symmetry as a possible physical mechanism.

  • Magnetic refrigeration leverages the magnetocaloric effect, necessitating materials with specific properties for optimal performance. Here, the authors explore Gd₂CrSbO₇, a mixed B-site pyrochlore oxide, revealing its significant cryogenic magnetocaloric effect driven by 4f–3d exchange interactions, positioning it as a cost-effective alternative to traditional refrigerants with potential for next-generation cooling technologies.
