Abstract
A heat pump system operates by the inverse magnetocaloric effect in which the working medium is a superconductive body of type II superconductive material having a critical temperature above 23.degree. K. The superconductive body is cooled to below its critical temperature and subjected to a changing magnetic field, which decreases the concentration of paired charged carriers without their complete elimination and induces cooling and/or absorbs heat of the working medium.
