Abstract

Spin-dependent conductance across a manganate-barrier-manganate junction has recently been demonstrated. The junction is a La_0.67Sr_0.33MnO₃-SrTiO₃-La _0.67Sr_0.33 MnO₃ trilayer device supporting current-perpendicular transport. Large magnetoresistance of up to a factor of five change was observed in these junctions at 4.2 K in a relatively low field of the order of 100 Oe. Temperature and bias dependent studies revealed a complex junction interface structure whose materials physics has yet to be understood.
