Large magnetically driven temperature changes are observed in MnFe(P,Si,B) materials simultaneously with large entropy changes, limited (thermal or magnetic) hysteresis, and good mechanical stability. The partial substitution of B for P in MnFe(P,Si) compounds is found to be an ideal parameter to control the latent heat observed at the Curie point without deteriorating the magnetic properties, which results in promising magnetocaloric properties suitable for magnetic refrigeration.
在 MnFe(P,Si,B)材料中同时观察到了大的磁驱动温度变化和大的熵变化、有限的（热或磁）滞后以及良好的机械稳定性。发现 MnFe(P,Si)化合物中 B 对 P 的部分取代是控制居里点观察到的潜热的理想参数，而不会恶化磁性，从而产生了有前途的磁热性能，适合于磁制冷。
