FIRST-PRINCIPLES STUDY OF THE LATTICE DYNAMICS, MAGNETIC, OPTICAL AND ELECTRONIC PROPERTIES OF CRYSTALS SrFeO<sub>3</sub> AND SrMnO<sub>3</sub>
In this work we study the ferroelectric, magnetic, optical and electronic properties of SrFeO3 and SrMnO3 crystals with the perovskite structure. The obtained results are providing compounds under consideration to be prospective candidates for application in electronic-controlled devices of microwave range, ultrafast optical modulators and analog capacitors of dynamic random access memory.
