Optimization of Discharge Parameters for a Glow Discharge Emission Spectrograph with Two-dimensional Spatial Resolution

Sputtering rate Sr was proposed as an alternative parameter instead of sputtering yield Y to calibrate the sputtering ability of the target, defined as the mass loss of the target per unit time and sputtering current. The approach is more reliable for glow discharge processes since the intense backscattering effect was taken into consideration. The effects of processing parameters on Sr were investigated through orthogonal test, the results indicated that target temperature affects Sr obviously, and among the discharge parameters, the target voltage and discharge pressure were the governing factors. Through regression analysis, the sputtering rate Sr was expressed as a function of sputtering voltage and discharge pressure which could be used to evaluate or predict the real output of the sputtering target.

Abstract Magnetic-domain structure and dynamics play an important role in understanding and controlling the magnetic properties of two-dimensional magnets, which are of interest to both fundamental studies and applications. However, the probe methods based on the spin-dependent optical permeability and electrical conductivity can neither provide quantitative information of the magnetization nor achieve nanoscale spatial resolution. These capabilities are essential to image and understand the rich properties of magnetic domains. Here, we employ cryogenic scanning magnetometry using a single-electron spin of a nitrogen-vacancy center in a diamond probe to unambiguously prove the existence of magnetic domains and study their dynamics in atomically thin CrBr3. The high spatial resolution of this technique enables imaging of magnetic domains and allows to resolve domain walls pinned by defects. By controlling the magnetic domain evolution as a function of magnetic field, we find that the pinning effect is a dominant coercivity mechanism with a saturation magnetization of about 26μB/nm2 for bilayer CrBr3. The magnetic-domain structure and pinning-effect dominated domain reversal process are verified by micromagnetic simulation. Our work highlights scanning nitrogen-vacancy center magnetometry as a quantitative probe to explore two-dimensional magnetism at the nanoscale.
