First-principles calculations to investigate physical properties of orthorhombic perovskite YBO (B = Ti & Fe) for high energy applications.

Orthorhombic oxide perovskite compounds are very promising materials for the applications of optoelectronics and thermal barrier coating. This work represents a numerical simulation of YBO compounds through the first-principles approach. The electronic and magnetic properties are investigated employing the general gradient approximation (GGA) coupled to the integration of the Hubbard U-term which is the GGA + U.
