We propose a new cryogenic refrigerator which is a hybrid of the Brayton magnetic-cooling cycle and the Gifford-McMahon (GM) gas-cooling cycle. We evaluate the refrigeration power of the refrigerator with an ErNi regenerator material by a numerical simulation. The results show a remarkably large refrigeration power in contrast to the conventional simple GM gas refrigerator.
