Traditional electronic products rely on the control of charge. Recently, researchers have been exploring a new technology called spintronics that relies on detecting and controlling the spin of particles. The use of this technology is expected to develop new devices that are more efficient and powerful. Recently, researchers at La Trobe University in Australia measured the interaction strength between the charge carrier spin and the diamond magnetic field. Research conclusions indicate that diamond materials have key properties for use in spintronic devices. Diamond is the focus of scientists because it is easier to process and manufacture into spintronic devices than traditional semiconductor materials. Traditional quantum devices are based on multi-semiconductor thin-layer structures, which require very precise manufacturing processes in ultra-high vacuum conditions. 
Background and Principles Diamond is a good insulator material, but when exposed to a hydrogen plasma environment, the diamond surface will adsorb and bind to the hydrogen atoms. The hydrogenated diamond exhibits the properties of the conductor in humid air because a thin film of water is formed on the surface of the diamond to extract electrons from the inside of the diamond. The surface of the diamond that loses electrons forms positively charged holes and thus has electrical conductivity. 
Researchers on diamond surface treated with hydrogen plasma have found that these holes have many characteristics that conform to spintronics, the most important of which is a relativistic effect called spin-orbit coupling, ie the spin angle of charge carriers. The interaction between momentum and orbital angular momentum. If this coupling is strong, researchers can use the electric field to control the spin of the charge carriers. In previous work, researchers have measured the spin-orbit coupling strength required to manipulate hole spins on diamond surfaces. They also found that the coupling strength can be adjusted by changing the external electric field. In a recent experiment, the researchers measured the interaction strength of holes and magnetic fields on the diamond surface. In the measurement experiment, the researchers applied a constant magnetic field of different intensity parallel to the diamond surface at a temperature lower than 4 Kelvin. At the same time, in the vertical direction, a stable magnetic field was applied to measure the resistance of the diamond. The change determines the Lande factor (g-factor). This value helps researchers use the magnetic field to control the spin of the device in the future. Meaning researchers pointed out that the strength of the spin coupling with electric and magnetic fields of the charge carriers is at the heart of spintronics. By obtaining the key parameters such as the spin-orbit coupling strength and the Lande factor of the system, the electric field or magnetic field regulation of the spin of the diamond conductive surface can be realized. 
In addition, the diamond is transparent, so it can also be integrated into the optics and manipulated with visible or ultraviolet light. The center of the nitrogen vacancy is a point-defect structure commonly found in diamond crystals, consisting of a nitrogen atom in the lattice that replaces a carbon atom and a vacancy on an adjacent lattice (as shown in the figure above). Its unique energy level structure and optical properties allow us to manipulate the spin state of its electrons by means of optical magnetic resonance; this spin state has a long coherence time at room temperature; at the same time, the surrounding nuclear spin provides a rich The hyperfine interactions can form a multi-qubit system. These properties make the nitrogen-vacancy center have great potential applications in quantum computing, high spatial resolution weak magnetic detection and temperature detection.
