Abstract

An elastic energy expression and a tight-binding Hamiltonian with electron-lattice coupling were used to study the effects of the in-plane strain on the orbital and magnetic properties of LaMnO3 thin films. The lanthanum compound possessed an orbital ordering below 750K and antiferromagnetic spin ordering below 140K. Tensile uniaxial strain of the order of 2% changed the magnetic ground state and the orbital state in the compound significantly.
