Abstract
The coupling between the electrical transport properties of (LSMO) thin films and structural phase transitions of (STO) substrates at has been investigated. We found that the electrical resistivity of LSMO films exhibit a “cusp” at , which is greatly amplified by tuning films to the verge of metallic and insulating phases, i.e., to the boundary of two delicate competing electronic states. Our results demonstrate that small amounts of strain can tip the subtle balance of competing interactions and tune the electronic properties in correlated electron materials.
