Future nanoscale technological applications in spintronics require research on two-dimensional materials with combined semiconductor and magnetic properties. We investigate transition metal dioxides in the form of layers, and we report on the structural and electronic properties of selected late transition metal d-elements. With half-filled d states, the MnO₂ and TcO₂ layers are magnetic semiconductors, and for side d-elements the CrO₂ and FeO₂ layers become half metals. These magnetic materials in 2D must be synthesized in order to assess their usefulness in future electronic and spintronic devices.

二维过渡金属二氧化物中的磁性和畸变：寻求本征磁性半导体层

自旋电子学中未来的纳米技术应用要求对具有半导体和磁学性质的二维材料进行研究。我们研究了层状过渡金属氧化物，并报告了选定的后期过渡金属d元素的结构和电子性质。在半填充d状态下，MnO ₂和TcO ₂层是磁性半导体，对于侧面d元素，CrO ₂和FeO ₂层变成半金属。必须以二维方式合成这些磁性材料，以评估其在未来电子和自旋电子设备中的用途。
