Oxygen-deficient dopant-free Ti3O5 and Ti2O3 ferromagnetic two-dimensional nanostructures for spin-based electronic devices

Abstract

In reduced two-dimensional titanium suboxide (TinO2n−1, n = 2, 3, 4…) nanostructures, exchange interactions between the reduced d1 ions and singly charged oxygen vacancy defects induce a remarkably strong dilute ferromagnetic property.
