Interface Magnetoresistance in Manganite-Titanate Heterojunctions
T. Susaki, N. Nakagawa, H. Y. Hwang
We have found that the current- voltage characteristics of La0.7Sr0.3MnO3(-delta)/Nb:SrTiO3 rectifying junctions are quantitatively well-described by (thermally-assisted) tunneling…

Why Some Interfaces Cannot be Sharp
Naoyuki Nakagawa, Harold Y. Hwang, David A. Muller
A central goal of modern materials physics and nanoscience is control of materials and their interfaces to atomic dimensions. For interfaces between polar and non-polar layers, thi…

Magnetocapacitance and exponential magnetoresistance in manganite-titanate heterojunctions
N. Nakagawa, M. Asai, Y. Mukunoki +2
We present a rectifying manganite-titanate heterojunction exhibiting a magnetic field tunable depletion layer. This creates a large positive magnetocapacitance, a direct measure of…
