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.
