Gd5Si2Ge2 属于一种称为超磁体的材料，该材料有望利用磁热效应现象应用于室温磁制冷。在这里，我们使用局部扫描霍尔探针对变磁转变进行成像，并揭示微观结构如何控制关键特性。
Gd5Si2Ge2 belongs to the class of materials known as metamagnets that show promise for application in room-temperature magnetic refrigeration using a phenomenon known as the magnetocaloric effect. Here we image the metamagnetic transition using a local scanning Hall probe and reveal how the microstructure controls the critical properties.
