First-Principles Investigation of Oxygen Vacancy Defects and Strain Engineering on the Electronic Structure and Magnetic Ordering in Perovskite SrTiO3: A DFT+U Framework
Perovskite strontium titanate (SrTiO3) is a model material system for the investigation of correlated electron effects, emergent interface properties, and functional spintronics. A prototypical non-magnetic band insulator SrTiO3, on the other hand, is often associated with defect-induced d0 ferromagnetism through intri...
