Cryogenic NV magnetometry is a powerful quantum sensing technique for nanoscale magnetic imaging across a broad temperature range (2 K to 300 K), with the ability to apply vector magnetic fields. This makes it uniquely suited for probing complex magnetic phenomena in emerging materials.
It is especially impactful in antiferromagnetic spintronics, where zero net magnetization and fast dynamics challenge conventional probes. NV magnetometry enables direct, non-invasive imaging of AFM domains and spin textures—key to realizing low-power, high-speed memory and logic devices. The ability to tune temperature and magnetic field orientation is essential for studying phase transitions, domain switching, and field-induced effects in AFMs and other correlated systems.
In quantum materials, it reveals local magnetic signatures in topological superconductors, skyrmion lattices, and quantum spin liquids. For semiconductors and quantum hardware, it supports cryogenic current mapping and defect analysis, critical for scalable quantum computing. In nanotechnology, it enables precise magnetic characterization of nanoscale devices under realistic operating conditions.
By combining quantum sensitivity, cryogenic operation, and vector field control, NV magnetometry is a uniquely versatile tool for advancing next-generation electronics and quantum technologies.
