Abstract

Procedimiento para el enfriamiento y licuación de helio y otros gases. El procedimiento comprende la realización de ciclos sucesivos del enfriamiento sobre la masa del gas a licuar con una mezcla de materiales dotados de temperaturas de transición magnética sucesivamente más reducidas, empezando aproximadamente en una temperatura de transición de 80 K y terminando en la temperatura de licuación del gas. Los materiales utilizados tienen preferentemente estructura de perovsquita.
