A versatile platform for angular-dependent magnetotransport measurements under low-temperature and high-pressure conditions

We present a versatile system capable of performing angular-dependent magnetic-field measurements under low-temperature and high-pressure conditions. In our design, the rotation module is mounted at the top of the sample chamber, where the rotating-seal technique prevents gas leakage during rotating. This setup allows any measuring probe inserted into the chamber to rotate synchronously within the magnetic field without requiring a specially designed sample holder. The configuration ensures precise angular control and minimizes mechanical errors arising from thermal contraction. Moreover, by configuring the pressure cell in horizontal or vertical modes, both in-plane rotation and in-plane to out-of-plane magnetic field rotation can be achieved. Overall, the system provides a universal and reliable platform for studying anisotropic magnetotransport behaviors of materials under extreme conditions, offering broad applicability to condensed matter physics and spintronic research.
