In this work it was performed a thorough theoretical study of structural, electronic and magnetic properties of the h-InMnO3 hexagonal manganite compound. As a computational tool it was employed the Full Potential Linearized Augmented Plane Wave electronic structure method, which is based on Density Functional Theory and implemented into the WIEN2k computer code. Exchange and correlation effects between the electrons were treated by the Generalized Gradient Approximation (GGA) functional, with addition of the Hubbard Ueff correction in order to correctly describe highly correlated Mn d-electrons. Three crystalline phases of the h-InMnO3 have been considered: the ferroelectric (FE) one (space group P63cm) and the two paraelectric (PE) ones (...
