Manipulation of phase transition in the phase-separated manganite films
The strong coupling effect between different degrees of freedom in the rare-earth manganites supplies rich possibilities for the modulation of physical properties,such as the magnetic properties,the d electron orbitals,and resistance states.Modulating the solid-state transition in the manganites thus exhibits high potential in achieving gi-ant magnetoelectric and electroresistance effects.Systematically reviews the group's work on the control of phase transition in the phase-separated rare-earth manganites.By introducing the static lattice strain,we have clarified that the anisotropic strain is the key to induce the antiferromagnetic transition.Following the guidance,we have chosen the(011)oriented PMN-PT as a substrate to fabricate the multiferroic heterostructures,by utilizing the e-lectric field-induced anisotropic strain in the substrate,the authors have obtained a giant magnetoelectric effect and electroresistance.
