A spin tunnel junction based on manganites, with La1−xSrxMnO3 LSMO as ferromagnetic metallic electrodes and the undoped parent compound LaMnO3 LMO as insulating barrier, is here theoretically discussed using double-exchange model Hamiltonians and numerical techniques. For an even number of LMO layers, the ground state is shown to have antiparallel LSMO magnetic moments. This highly resistive, b...

Multiferroic heterojunctions are promising for application in low-power storage and spintronics due to their magnetoelectric coupling properties. Controlling the magnetic transport properties of materials by external stimuli then realizing advanced devices constitute key mission this field. We fabricated a multiferroic heterostructure consisting ferroelectric single-crystal (001)-0.7Pb(Mg1/3Nb2...

kinetic monte carlo simulation was applied to investigation of kinetics and mechanism of oxalic acid degradation by direct and heterogeneous catalytic ozonation. la-containing perovskites including lafeo3, lanio3, lacoo3 and lamno3 was studied as catalyst for oxalic acid ozonation. the reaction kinetic mechanisms of each abovementioned catalytic systems has been achieved. the rate constants val...
