Here, we report on a versatile full angular resolved/broad temperature range/vectorial magneto optical Kerr effect (MOKE) magnetometer, named TRISTAN. Its versatility relies on its capacity to probe temperature and angular dependencies of magnetization reversal processes without the need to do any intervention on the apparatus during measurements. The setup is a combination of a vectorial MOKE bench and a cryostat with optical access. The cryostat has a motorized rotatable sample holder with azimuthal correction. It allows for simultaneous and quantitative acquisition of the two in-plane magnetization components during the hysteresis loop at different temperatures from 4 K up to 500 K and in the whole angular range, without neither changing magnet orientation nor opening the cryostat. Measurements performed in a model system with competing collinear biaxial and uniaxial contributions are presented to illustrate its capabilities.
在此，我们报告一种多功能的全角度分辨/宽温度范围/矢量磁光克尔效应（MOKE）磁力计，名为TRISTAN。其多功能性依赖于它能够探测磁化反转过程的温度和角度依赖性，而在测量过程中无需对仪器进行任何干预。该装置是矢量MOKE工作台和带有光学通道的低温恒温器的组合。低温恒温器有一个带方位校正的电动旋转样品架。它允许在4K至500K的不同温度下以及在整个角度范围内，在磁滞回线期间同时定量采集两个面内磁化分量，而无需改变磁体方向或打开低温恒温器。在具有竞争共线双轴和单轴贡献的模型系统中进行的测量结果被展示以说明其性能。
