· JVASP-91848· LaFe5H2

LaFe5H2 is an intermetallic hydride compound combining lanthanum, iron, and hydrogen, belonging to the rare-earth metal hydride family. This material is primarily investigated in research contexts for magnetocaloric and hydrogen storage applications, where its ability to absorb and release hydrogen and undergo magnetic transitions under modest field changes makes it attractive for next-generation cooling systems and energy storage. Engineers would consider this compound for advanced thermal management or hydrogen-related energy systems where traditional refrigeration or storage methods are insufficient or inefficient.
