Optical probe of electrostatic doping in an n-type Mott insulator (2007)

Nakamura, M., Sawa, A., Sato, H., Akoh, H., Kawasaki, M., Tokura, Y.

Electrostatic doping into an $n$-type Mott insulator Sm$_{2}$CuO$_{4}$ has been successfully achieved with use of the heterojunction with an $n$-type band semiconductor Nb-doped SrTiO$_{3}$. The...

Hysteretic current-voltage characteristics and resistance switching at an epitaxial oxide Schottky junction SrRuO$_{3}$/SrTi$_{0.99}$Nb$_{0.01}$O$_{3}$ (2004)

Fujii, T., Kawasaki, M., Sawa, A., Akoh, H., Kawazoe, Y., Tokura, Y.

Transport properties have been studied for a perovskite heterojunction consisting of SrRuO$_{3}$ (SRO) film epitaxially grown on SrTi$_{0.99}$Nb$_{0.01}$O$_{3}$ (Nb:STO) substrate. The SRO/Nb:STO...

Hysteretic current-voltage characteristics and resistance switching at a rectifying Ti/Pr$_{0.7}$Ca$_{0.3}$MnO$_{3}$ interface (2004)

Sawa, A., Fujii, T., Kawasaki, M., Tokura, Y.

We have characterized the vertical transport properties of epitaxial layered structures composed of Pr$_{0.7}$Ca$_{0.3}$MnO$_{3}$ (PCMO) sandwiched between SrRuO$_{3}$ (SRO) bottom electrode and...

Spin-polarized tunneling of La0.67Sr0.33MnO3/YBa2Cu3O7-d junctions (1999)

Sawa, A., Kashiwaya, S., Obara, H., Yamasaki, H., Koyanagi, M., Yoshida, N., ...

The transport properties between ferromagnets and high-Tc superconductors are investigated in La0.67Sr0.33MnO3/YBa2Cu3O7-d (LSMO/YBCO)junctions in the geometry of cross-strip lines. The conductance...

Calcium requirements for electrically-induced release of an endogenous opiate receptor ligand from the guinea-pig ileum.

Oka, T, Sawa, A

Calcium requirements for electrically-induced release of an endogenous opiate receptor ligand in the myenteric plexus-longitudinal muscle strip of the guinea-pig ileum were studied. The...
