Room temperature ferroic orders in Zr and (Zr, Ni) doped SrTiO3

We synthesized strontium titanate SrTiO3 (STO), Zr doped Sr1−xZrxTiO3 and (Zr, Ni) co-doped Sr1−xZrxTi1−yNiyO3 samples using solid state reaction technique to report their structural, electrical magnetic properties. The cubic Pm-3m phase of the has been confirmed Rietveld analysis powder X-ray diffraction pattern. grain size materials was reduced significantly due doping as well co-doping in STO. chemical species were identified energy-dispersive spectroscopy (EDX). Ni dopants’ homogeneity from EDX mapping negate spurious ferroic order dopant segregation. observed forbidden first Raman scattering at 148, 547 797 cm−1 which may indicate nominal loss inversion symmetry absence absorption 500 within 600–700 band Fourier Transform Infrared spectra corroborates substitutional dopants our samples. Due 4% Sr0.96Zr0.04TiO3 sample dielectric constant, remnant electric polarization, magnetization coercivity increased. Notably, case 10% we have clearly existence both FE FM hysteresis loops Sr0.96Zr0.04Ti0.90Ni0.10O3 sample. In this sample, increased by ∼1 ∼2 orders magnitude respectively compared those undoped coexistence STO might potential for interesting multiferroic applications.
