Summary

The authors have investigated the characteristics of some layered structural regenerators (multilayer regenerators) with magnetic regenerator materials using a two-stage Gifford-McMahon refrigerator. In the study, they newly used erbium(0.75)-gadolinium(0.25)-nickel which is expected to be placed in the high-temperature part of the second regenerator. With the triplelayer regenerator, the lowest temperature was 2.60 K at the second stage and the maximum refrigeration capacity at 4.2 K was 1.17 watt. These results were superior to those with the doublelayer regenerator.
