Electronic structures and optical properties of layered perovskites Sr_2MO_4 (M=Ti, V, Cr, and Mn): An ab initio study

Hongming Weng, Y. Kawazoe, Xiangang Wan +1

A series of layered perovskites Sr${}_2$$M$O${}_4$ ($M$=Ti, V, Cr, and Mn) is studied by $ab$ $initio$ calculations within generalized gradient approximation (GGA) and GGA+$U$ schemes…
