描述了一种用于高各向异性材料磁输运测量的系统。一种类型的低温恒温器可以在±15°的角度范围内绕两个水平轴旋转样品，分辨率为± 0.02°，而另一种可以在更宽的范围内绕一个轴旋转样品，分辨率为± 0.1°。这些样品架在7 T超导分裂线圈磁体产生的水平磁场中由计算机控制的步进电机以0.0036°/步的分辨率绕垂直轴旋转。最后给出了几个利用该系统进行的测量实例，以说明该系统的性能。
A system useful for magnetotransport measurement on highly anisotropic materials is described. One type of cryostat can rotate a sample about two horizontal axes over an angular range of ∼±15° with a resolution of ∼0.02°, while another can rotate it about one axis over a wider range with a resolution of ∼0.1°. These sample holders are rotated about a vertical axis by a computer‐controlled stepping motor with a 0.0036°/step resolution in a horizontal magnetic field generated by a 7 T superconducting split‐coil magnet. A few examples of measurements recently made by use of this system are given to illustrate the system’s performance.
