Title: Giant reversible anisotropy changes at room temperature in a (La,Sr)MnO₃/Pb(Mg,Nb,Ti)O₃ magneto-electric heterostructure

Abstract

In a model artificial multiferroic system consisting of a (011)-oriented ferroelectric Pb(Mg,Nb,Ti)O ₃ substrate intimately coupled to an epitaxial ferromagnetic (La,Sr)MnO ₃ film, electric field pulse sequences of less than 6 kV/cm induce large, reversible, and bistable remanent strains. The magnetic anisotropy symmetry reversibly switches from a highly anisotropic two-fold state to a more isotropic one, with concomitant changes in resistivity. Anisotropy changes at the scale of a single ferromagnetic domain were measured using X-ray microscopy, with electric-field dependent magnetic domain reversal showing that the energy barrier for magnetization reversal is drastically lowered. Free energy calculations confirm this barrier lowering by up to 70% due to the anisotropic strain changes generated by the substrate. Thus, we demonstrate that an electric field pulse can be used to 'set' and 'reset' the magnetic anisotropy orientation and resistive state in the film, as well as to lower the magnetization reversal barrier, showing a promising route towards electric-field manipulation of multifunctional nanostructures at room temperature.

Electric-field-controlled interface strain coupling and non-volatile resistance switching of La{sub 1-x}Ba{sub x}MnO₃ thin films epitaxially grown on relaxor-based ferroelectric single crystals

Journal Article Zheng, Ming ; Zhu, Qiu-Xiang ; Li, Xue-Yan ; ... - Journal of Applied Physics

We have fabricated magnetoelectric heterostructures by growing ferromagnetic La{sub 1-x}Ba{sub x}MnO₃ (x=0.2, 0.4) thin films on (001)-, (110)-, and (111)-oriented 0.31Pb(In{sub 1/2}Nb{sub 1/2})O₃-0.35Pb(Mg{sub 1/3}Nb{sub 1/2})O₃-0.34PbTiO₃ (PINT) ferroelectric single-crystal substrates. Upon poling along the [001], [110], or [111] crystal direction, the electric-field-induced non-180° domain switching gives rise to a decrease in the resistance and an enhancement of the metal-to-insulator transition temperature T_C of the films. By taking advantage of the 180° ferroelectric domain switching, we identify that such changes in the resistance and T_C are caused by domain switching-induced strain but not domain switching-induced accumulation or depletion of charge carriers atmore »« less

Colossal anisotropic resistivity and oriented magnetic domains in strained La{sub 0.325}Pr{sub 0.3}Ca{sub 0.375}MnO{sub 3} films

Journal Article Jiang, Tao ; Yang, Shengwei ; Liu, Yukuai ; ... - Applied Physics Letters

Magnetic and resistive anisotropies have been studied for the La{sub 0.325}Pr{sub 0.3}Ca{sub 0.375}MnO{sub 3} films with different thicknesses grown on low symmetric (011)-oriented (LaAlO{sub 3}){sub 0.3}(SrAl{sub 0.5}Ta{sub 0.5}O{sub 3}){sub 0.7} substrates. In the magnetic and electronic phase separation region, a colossal anisotropic resistivity (AR) of ∼10{sup 5}% and an anomalous large anisotropic magnetoresistance can be observed for 30 nm film. However, for 120 nm film, the maximum AR decreases significantly (∼2 × 10{sup 3}%) due to strain relaxation. The colossal AR is strongly associated with the oriented formation of magnetic domains, and the features of the strain effects are believed to bemore »« less

Field-Induced Spin-Modulated Transitions in Epitaxial (001) BiFeO{sub 3} Films

Journal Article Kulagin, N. E. ; Popkov, A. F. ; Solov’yov, S. V., E-mail: sv.soloviov@yandex.ru ; ... - Physics of the Solid State

Alterations in the ground state of thin (001) films of a BiFeO{sub 3} (BFO)-type multiferroic in a magnetic field are studied theoretically, with changes in the energy of induced anisotropy taken into account. The anisotropy vs. field phase diagrams identifying the stability regions of homogeneous antiferromagnetic states and the regions of emergence of spatially modulated antiferromagnetic states are constructed for three mutually orthogonal orientations of applied magnetic field. We show that, as the magnetic field decreases, the transformation of a homogeneous phase into a spatially modulated state occurs at the instability point of the homogeneous state via gradual emergence ofmore »« less

Influence of dislocations and twin walls in BaTiO₃ on the voltage-controlled switching of perpendicular magnetization

Journal Article Goiriena-Goikoetxea, M. ; Xiao, Z. ; El-Ghazaly, A. ; ... - Physical Review Materials

In this work, we investigate the influence of dislocations and twin walls in BaTiO₃ on its ferroelectric response and the resulting effect on the perpendicular magnetic anisotropy (PMA) of a strain-coupled [Co\Ni]_n film. A dense twinned structure in conjunction with a high dislocation density significantly reduces the converse piezoelectric effect of BaTiO₃ by hindering the propagation of newly nucleated domains with an applied electric field. This, in turn, results in a modest reduction of the PMA of the ferromagnetic layer. On the other hand, the ferroelectric polarization reorients from [100] to [001] direction in a dislocation-free BaTiO₃, inducing the maximummore »« less

Magnetotransport characteristics of strained La{sub 0.7}Sr{sub 0.3}MnO{sub 3} epitaxial manganite films

Journal Article Ovsyannikov, G. A., E-mail: gena@hitech.cplire.ru ; Petrzhik, A M ; Borisenko, I V ; ... - Journal of Experimental and Theoretical Physics

The electrical and magnetic characteristics of La{sub 0.7}Sr{sub 0.3}MnO{sub 3} (LSMO) epitaxial manganite films are investigated by different methods under conditions when the crystal structure is strongly strained as a result of mismatch between the lattice parameters of the LSMO crystal and the substrate. Substrates with lattice parameters larger and smaller than the nominal lattice parameter of the LSMO crystal are used in experiments. It is shown that the behavior of the temperature dependence of the electrical resistance for the films in the low-temperature range does not depend on the strain of the film and agrees well with the resultsmore »« less
