Carrying forward 2024 and Linking up the New Year：Cryogenic Scanning Nitrogen-vacancy Microscope Delivered to City University of Hong Kong

Recently, the CIQTEK-developed Cryogenic Scanning Nitrogen-vacancy Microscope (SNVM) was successfully delivered to Professor Wong Chun-ling's research group at the City University of Hong Kong. This marks the broader recognition of CIQTEK's technical strength and service capability in the field of precision measurement.

Magnetism is one of the fundamental properties of materials, and the microscopic imaging of magnetism is an important direction in experimental physics research. By studying the microscopic magnetic properties of materials in depth, scientists can gain insights into the structure, electronic properties, and interactions of materials, which is of great significance for guiding the development of new magnetic storage materials and superconducting materials.

The Cryogenic Scanning Nitrogen-vacancy Microscope is a precision measurement instrument that combines diamond NV center optical detection of magnetic resonance technology with atomic force microscopy scanning imaging technology. It can be used for high-resolution, high-sensitivity, quantitative, and non-destructive magnetic measurements in a wide temperature range of 2K to 300K. It has nanoscale spatial resolution and ultra-high detection sensitivity of single spins. It will provide a new approach for research in life sciences, materials science, condensed matter physics, and other fields.

City University of Hong Kong is a public research university located in Hong Kong, renowned for its outstanding research and education in disciplines such as science, engineering, business, and law. Professor Wong Chun-ling's research group focuses on the study of two-dimensional and three-dimensional ferromagnetic and multiferroic materials and devices. By manipulating materials, and characterizing their structures and electrical/magnetic properties, the group aims to gain a deep understanding of the fundamental physics and unique properties of low-dimensional multiferroic materials and develop new materials/devices for the next generation of electronics and spintronics. The Cryogenic Scanning Nitrogen-vacancy Microscope will be an important scientific research tool in the field.
