Photoelectric conductivity of SrTi1-xNixO3 driven by orbital and magnetic field

Abstract

SrTiO3 is known as high thermoelectric and ferroelectric materials. Introducing different orbitals may produce an anomalous optoelectrical effect. SrTiO3 perovskite provides d0 configuration with an energy gap of 3.2 eV and possesses ferroelectric properties. Ni with a various valence of +2, +3, +4 could be used to replace at Ti site in SrTiO3 compound will modify the normal octahedral configuration, in turn, it changed a micro elastic, crystal field, or coulomb interactions. Macroscopically, we will observe the physical properties of, e.g., magnetoelectric conductivity. SrTi1-xNixO3 was prepared by a solid-state reaction. The crystal structure of SrTi1-xNixO3 was analyzed by XRD. Electrical properties were carried out by inducing a magnetic field and light illumination during dielectric and electrical conductivity measurements, respectively.
