研究了适合于制备大块非晶合金的FeCrMoCuGaPCB系列合金的磁热效应。最佳的制冷循环具有接近室温的蓄冷器。这些合金的制冷容量与含Mo的Finemet型合金相当，并且比具有可比工作温度的其他块体非晶合金大40%。分析了磁场对磁熵变的影响，结果表明，在所有的磁区，磁熵变都服从幂律。
The magnetocaloric effect of the FeCrMoCuGaPCB alloy series, suitable for being prepared as bulk amorphous alloys, has been studied. Optimal refrigeration cycles have a cold reservoir close to room temperature. The refrigerant capacity of these alloys is comparable to that of a Mo-containing Finemet-type alloy and is ∼40% bigger than that of other bulk amorphous alloys with comparable working temperatures. Analysis of the field dependence of the magnetic entropy change evidences a power law for all the magnetic regimes.
