Abstract

Método para enfriar que comprende los pasos siguientes en: áplicar una presión P1 a un material para enfriar, mientras se mantiene la temperatura sensiblemente constante de tal modo que ocurra una transición de fase desde un primer estado de cristal a un segundo estado de cristal durante la cual se altera la interacción del campo de cristal de dicho material para enfriar, éjecutar una despresurización adiabática por aplicación de una presión positiva P2 si la presión P1 es negativa, o una presión negativa P2 si la presión P1 es positiva, a dicho material para enfriar con el n de restituirlo nuevamente a dicho primer estado de cristal o cercano al mismo para que disminuya la temperatura de dicho material para enfriar.
