Cryogenic Vertical Superconducting Magnetic Field Probe Station
The PS1DP-Cryo closed-loop cryogenic superconducting magnet probe station, based on a 4 K closed-loop cryogenic probe station, adds a ±3 T superconducting magnet, providing a low-temperature strong magnetic field environment for 2-inch samples. It can accommodate samples for electrical transport testing of 2D materials, spintronic devices, superconducting materials, and Hall effect testing of semiconductor materials or devices. The probe station provides comprehensive control and testing software for automated and systematic testing solutions. Users can monitor and control the temperature and magnetic field of the probe station in real-time via software, and perform testing sequences for magnetoresistance, second harmonic, Hall effect, SOT, etc., making it an efficient solution for electrical transport characterization under low-temperature strong magnetic fields.
