Abstract
We have investigated the effect of uniaxial pressure (P) on electrical resistivity along the ab plane and c axis in a single crystal of Sm0.55(Sr0.5Ca0.5)0.45MnO3. A huge piezoresistance (PR ∼107% at P = 90 MPa) and a remarkable increase (at the rate of ∼79 K/GPa) of metal-insulator transition temperature (TMI) have been observed for P applied along the c axis, while TMI decreases at the rate of ∼77 K/GPa for P perpendicular to the c axis. These values of PR and dTMI/dP are much larger than those observed in other perovskite and bilayer manganites. Such colossal PR and large value of dTMI/dP may be utilized for various technological applications.
