Research Abstract

In order to control the charge and orbital ordered pattern by epitaxial strain, Nd_<0.25>Sr_<1.75>MnO_4 thin films were fabricated on the (100) surface of LaSrGaO_4 and LaSrAlO_4 substrates. Due to the anisotropic strain in the MnO_2 plane, the orientation-controlled films were stabilized. Measurements of highly anisotropic optical spectra indicate that the direction of the ferroic ordering of d_<3x2-r2> orbitals can be controlled by external uniaxial pressure, implying a potential for a switching device combined with piezoelectric crystals.
