Two-dimensional van der Waals (2D vdW) materials are widely used in spin-orbit torque (SOT) devices. Recent studies have demonstrated the low crystal symmetry and large spin Hall conductivity of 2D vdW ZrSe3, indicating its potential applications low-power SOT Here, we study interfacial contribution SOTs current-induced magnetization switching ZrSe3/Py (Ni80Fe20) ZrSe3/Cu/Py heterostructures. efficiencies samples detected by spin-torque ferromagnetic resonance (ST-FMR), out-of-plane...
Chemical mechanical polishing (CMP) process has become a widely accepted global planarization technology. Abrasive is one of the key elements in CMP. In present paper, series novel Ti-doped colloidal SiO2 composite abrasives were prepared by seed-induced growth method. The CMP performances on (0001) plane sapphire substrates investigated. analyses surfaces polished indicate slurries containing achieve lower surface roughness and higher material removal rate than that pure abrasive. X-ray...
Magnetic texture in a chiral material is touted as one of the next-generation nonvolatile computing elements. Thermal manipulation magnetic textures attracts considerable attention and has promising applications. Here, temperature-dependent properties Ta/CoFeB/MgO thin film are studied experimentally theoretically. We report controllable spin distribution with temperature gradient film. The nucleation area could be generated at certain location through cooperation heat field. This method...
Skyrmions have attracted significant interest due to their topological spin structures and fascinating physical features. The skyrmion phase arises in materials with a Dzyaloshinskii–Moriya interaction at interfaces or volume of non-centrosymmetric materials. Although skyrmions been demonstrated experimentally, the general critical intrinsic relationship among fabrication, microstructures, magnetization, existence remains be established. Here, two series CoFeB ultrathin films controlled...
The spin transfer torque (STT) based magnetic random access memory (MRAM) device has been seen as the next general storage which can realize non-volatile and in-memory computing. However, shape defect that comes from fabrication process will influence performance of MRAM device. In this work, relationship between critical current switching time interface edge in a CoFeB is studied by atomistic model. simulations effect depends on thickness layer, operating temperature driven density. Our...
Magnetic random-access memory (MRAM) is one of the most promising next-generation purpose devices for nonvolatile storage and in-memory computing. However, material defects can affect performance MRAM device. Here, relationship between properties CoFeB–MgO-based have been studied with micromagnetic simulations. The results show that coercivity switching speed are strongly influenced by defects. This work provides a useful guideline fabrication MARM devices.
