Interface-sensitive nuclear magnetic resonance at a semiconductor heterojunction using hyperpolarization
Atsushi Goto, Kenjiro Hashi, Shinobu Ohki +1
We demonstrate an interface-sensitive NMR in a semiconducting nanostructure, where an NMR signal from the minute heterojunction region of a model heterojunction structure (In$_{0.4…
NMR study of thermally activated paramagnetism in metallic low-silica X zeolite filled with sodium atoms
Mutsuo Igarashi, Takehito Nakano, Pham Tan Thi +8
We report a \^{23}Na and \^{27}Al nuclear magnetic resonance (NMR) investigation of low-silica X (LSX) zeolite with chemical formula Na_{12}Al_{12}Si_{12}O_{48} (Na_{12}-LSX) loade…
Surface-sensitive NMR in optically pumped semiconductors
Atsushi Goto, Tadashi Shimizu, Kenjiro Hashi +1
We present a scheme of surface-sensitive nuclear magnetic resonance in optically pumped semiconductors, where an NMR signal from a part of the surface of a bulk compound semiconduc…
Dynamics of the electron-nuclear and heteronuclear polarization transfers in optically-oriented semi-insulating InP:Fe
Atsushi Goto, Kenjiro Hashi, Tadashi Shimizu +1
Dynamics of the electron-nuclear and heteronuclear polarization-transfer processes in the optically oriented semi-insulating iron-doped indium phosphide were investigated through t…
Optical pumping NMR in the compensated semiconductor InP:Fe
Atsushi Goto, Kenjiro Hashi, Tadashi Shimizu +6
The optical pumping NMR effect in the compensated semiconductor InP:Fe has been investigated in terms of the dependences of photon energy (E_p), helicity (sigma+-), and exposure ti…
Spin Susceptibility and Superexchange Interaction in the Antiferromagnet CuO
T. Shimizu, T. Matsumoto, A. Goto +3
Evidence for the quasi one-dimensional (1D) antiferromagnetism of CuO is presented in a framework of Heisenberg model. We have obtained an experimental absolute value of the parama…
