具有多孔结构的LaFe(13-x)6合金在循环过程中不会机械降解，并保持其出色的冷却性能，这是以前无法获得的。通过调节微晶尺寸来控制磁热效应和磁滞回线的能力保证了这些材料在磁制冷和多孔性材料中的应用，这些材料在各种与能源相关的应用中通常表现出一级转变。
LaFe(13-x)Six alloys with porous architecture do not degrade mechanically during cycling and maintain their excellent cooling performance, which was not accessible before. The ability to control the magnetocaloric effect and hysteresis by tuning of crystallite size promises applicability of these materials in magnetic refrigeration and porous materials exhibiting a first-order transition in general in diverse energy-related applications.
