Comparative study of multiferroic properties of PbTi0.5Fe0.5O3 thin films grown on various substrates

Multiferroic PbTi0.5Fe0.5O3 films are grown by using pulsed laser deposition technique on Si, Pt/Ti/SiO2/Si and SrRuO3/Si substrates. It is found that the PbTi0.5Fe0.5O3 films get modified from tetragonal to orthorhombic while deposited on Si substrate unlike the other two substrates. For Pt/Ti/SiO2...

Summary:Multiferroic PbTi0.5Fe0.5O3 films are grown by using pulsed laser deposition technique on Si, Pt/Ti/SiO2/Si and SrRuO3/Si substrates. It is found that the PbTi0.5Fe0.5O3 films get modified from tetragonal to orthorhombic while deposited on Si substrate unlike the other two substrates. For Pt/Ti/SiO2/Si and SrRuO3/Si substrates the crystal structure remains tetragonal. More importantly, the magnitude of ferroelectric, magnetic polarization and magneto-electric coupling observed in both tetragonal and orthorhombic phases are good enough for a variety of device applications. It gives flexibility for selecting substrate while fabricating PbTi0.5Fe0.5O3 based multifunctional devices.
