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. Copyright © 2019 American Chemical Society.
