Description
Summary:Room temperature ferromagnetism with large saturation magnetism was first observed in layered TiO2 (LT). The LT is in rich of oxygen vacancy and free of magnetic transition metal elements. The temperature dependence of magnetism indicates that carrier mobility and carrier number of LT are larger than that of anatase TiO2 (AT) and amorphous TiO2 (AMT). The room temperature ferromagnetism is an intrinsic property of LT since there are no magnetic transition metal elements in LT. LT is a good platform to study two-dimensional (2D) magnetism.
