AI Technical Summary
In existing technologies, the characterization of the electrical transport properties and quantum magnetic behavior of materials requires separate equipment, which leads to low efficiency and systematic errors. It is impossible to acquire electromagnetic signals simultaneously in the same high-voltage microenvironment, and traditional devices cannot achieve in-situ, coordinated characterization under extreme conditions.
An in-situ electro-transport and quantum magnetics co-characterization system was designed, including a multi-physics coupling module, a co-detection module, and a position adjustment and vibration isolation module. By integrating nitrogen-vacancy color centers and metal thin film electrodes through a diamond anvil cell, and combining a vector superconducting magnet and a cryogenic isothermal device, synchronous characterization under extreme conditions can be achieved.
It achieves high-precision in-situ coordinated characterization under multi-physics field coupling environments such as high pressure, strong magnetic field, and low temperature, eliminates errors introduced by environmental differences, and provides a powerful experimental tool for revealing the physical mechanisms of complex quantum materials.
