## Description

- description: Cryogenic cooling technology, widely used in medical applications such
    as magnetic resonance imaging and other fields, relies heavily on critical resources,
    including helium gas and heavy rare-earth elements. With the growing demand for
    cryogenic cooling in the near future, the development of alternative technologies
    that do not depend on such scarce resources has become imperative. This study
    introduces cold storage materials, known as regenerator materials, made from abundant
    elements such as copper, iron, and aluminum. These regenerator materials function
    as Gifford-McMahon cryocoolers. By utilizing the significant magnetic heat capacity
    generated through the "spin frustration" effect—a phenomenon arising from competition
    among magnetic interactions—the regenerator material CuFe1₋xAlxO2 achieves cooling
    below the helium condensation temperature. Notably, its cooling capacity below
    10 K shows performance comparable to conventional materials based on heavy rare-earth
    elements. This work shows the potential of using non-rare-earth magnetic materials
    as cryogenic regenerator materials and contributes to the development of environmentally
    sustainable cryogenic cooling technologies, paving the way for a cleaner and more
    sustainable future.
