Quantum Diamond Microscope (QDM)

Diamond V

CIQTEK Quantum Diamond Microscope (QDM) is a wide-field magnetic resonance based on the principle of spin magnetic resonance in the diamond nitrogen-vacancy center (NV center). The spin quantum state of the NV center luminescence defects is susceptible to the surrounding microwave and static magnetic fields and can be read out using a laser.
Measuring the magnetic or microwave field distribution around the sample using NV centers enables quantitative nondestructive microscopic magnetic imaging with high spatial resolution, a large field of view, a large dynamic range of detectable magnetic fields, and fast imaging speed.
It's also compatible with ambient testing environments to cryogenic & vacuum extreme environments.

Ultra-high spatial resolution

Quantitatively non-invasive magnetic imaging

Applications

Geological magnetism/Paleomagnetism

Geological rocks have different magnetic properties since their formation by magnetization of the geomagnetic field. By researching the remains of magnetism in geological samples, we can understand the strength and square of the earth's magnetic field in the past.

Generally, this magnetism is measured by measuring the volume in millimeters to centimeter samples to analyze the net magnetic moment. However, at the scale of submillimetre, geological samples are often heterogeneous in structure, and only a small fraction of ferromagnetic particles carry magnetism.

CIQTEK Quantum Diamond Microscope with the magnetic measurement sensitivity of 5μT√HZ, 400 nm spatial resolution, and 1 mm² field of view, so the geological samples could be remanent magnetized and achieve induction magnetization imaging.

Cellular magnetic imaging

CIQTEK Quantum Diamond Microscope could reach a high spatial resolution technology in the operating conditions of living biological samples than traditional magnetic imaging technology. By placing live cells (magnetotactic bacteria) upon the surface of NV centers and measuring the magnetic imaging with subcellular 400nm high spatial resolution, The magnetic imaging of living cells shows great value in the biological research area.

2D Van DerWaals magnets have all sorts of emerging anomalies including special magnetism. 2D Van Der Waals materials include insulators, semiconductors, and superconductors, etc. They have broad application prospects in spintronics and ultra-compact magnetic memory media. CIQTEK Quantum Diamond Microscope can not only directly image 2D van der Waals magnets material but also magnetized the materials by changing the external magnetic field and exploring the origin of ferromagnetism and domain wall dynamics under external field regulation.

Characterization of chip current

The current density distribution of the chip will generate magnetic field distribution in space, which contains the structure and function of the circuit information, which has an important meaning in the semiconductor industry. When the NV center resonates, the fluorescence intensity will decrease. The NV center diamond is pasted on the surface of chips, and the resonance frequency can be determined by measuring the fluorescence intensity of NV, and the magnetic field distribution around the chip can be determined. CIQTEK Quantum Diamond Microscope can be used to learn the operation behavior of integrated circuits during chip task execution.

Bio-magnetism

Iron is one of the important mineral elements in biological issues, so magnetism is an indispensable characteristic of biological minerals. However, in the process of biological mineralization, the magnetic state, magnetic structure, and magnetic orientation of minerals will be lost. CIQTEK Quantum Diamond Microscope can provide a new way to directly detect these biological systems, which can characterize the detailed magnetic information of biological minerals. we can study the ferromagnetic sequence of iron minerals in the early stage of mineralization in organisms.
