We present a novel instrument designed for advanced magnetic study, installed at the ID12 beamline of the European Synchrotron Radiation Facility in Grenoble, France. This instrument offers the unique capability to simultaneously measure element-specific microscopic and macroscopic properties related to the magnetic, electronic and structural characteristics of materials. In addition to X-ray absorption, X-ray magnetic circular dichroism alongside X-ray diffraction patterns, the macroscopic magnetization, volume changes, caloric properties and electrical resistivity of magnetic materials could be measured strictly under the same experimental conditions as a function of both magnetic field (up to ±7 T) and temperature (ranging from 2.05 K to 325 K). To demonstrate the capability of this new instrument, we present two case studies highlighting its performance in investigating first-order magneto-structural phase transitions, namely in DyCo and FeRh alloys.
我们展示了一种专为先进磁性研究设计的新型仪器,该仪器安装在法国格勒诺布尔欧洲同步辐射装置的ID12光束线上。该仪器具有独特的能力,能够同时测量与材料的磁性、电子和结构特性相关的特定元素的微观和宏观性质。除了X射线吸收、X射线磁圆二色性以及X射线衍射图谱外,磁性材料的宏观磁化强度、体积变化、热性质和电阻率可以在与磁场(高达±7 T)和温度(范围从2.05 K至325 K)相关的相同实验条件下严格测量。为了展示这种新仪器的能力,我们给出了两个案例研究,突出了其在研究一阶磁结构相变方面的性能,即在DyCo和FeRh合金中的性能。
