Low temperature strong magnetic field magnetic resonance microscope attoCSFM

Low temperature strong magnetic field magnetic resonance microscope attoCSFM

Optically detected magnetic resonance (ODMR), as a magnetic imaging technology, has developed for decades and has the characteristics of high sensitivity and spatial resolution of several nanometers to distinguish the spin magnetism of individual electrons and atomic nuclei. It has become a cutting-edge experimental technology. Moreover, compared to existing methods for measuring the magnetic properties of samples, such as transmission X-ray spectroscopy and magnetic atomic force microscopy, ODMR also has the characteristics of no disturbance to the magnetic properties of samples and qualitative measurement of magnetic properties. The company provides an ideal platform for ODMR: the attoCSFM system integrates high numerical aperture (NA) confocal microscopy and atomic force microscopy prepared from completely non-magnetic materials to meet the needs of ODMR experiments. From an application perspective, atoCSFM is an ideal choice for studying the next generation of high-density magnetic memory, as well as a new tool for developing and researching new applications in spintronics and quantum technology. Its emergence solves the basic problem of nanoscale magnetic imaging and has wide applications in materials science, superconducting science, and biological science research.
