Nuclear Magnetic Resonance in a Ferromagnet-Semiconductor Heterostructure
We report the observation of nuclear magnetic resonance (NMR) in a ferromagnet-semiconductor heterostructure in the presence of a spin-polarized current. Spin-polarized electrons injected from a metallic ferromagnet generate a large nuclear spin population in a GaAs quantum well by dynamic polarization. The characteristic time for the polarization process is approximately 20 sec, and the nuclea...
متن کاملNUCLEAR MAGNETIC RESONANCE STUDY OF THE STRUCTURE OF GLYOXALDIHYDRAZONE
Study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure
متن کاملA Nuclear Magnetic Resonance Study
Complexes of histidine with Co( 11) in aqueous solution have been examined by proton magnetic resonance spectroscopy. Coordinate interaction of histidine with paramagnetic Co( 11) produces large contact interaction shifts in the histidine proton resonance spectra. Four histidine-Co( 11) complexes have been distinguished : a weak 1: 1 histidine-Co(I1) complex a t low pH ( < 4 ) in which only the...
متن کاملComputational study of energetic, stability, and nuclear magnetic resonance of BN nanotube as a nanosensor
Now a day study on boron nitrid nanotubes are in considerable attetion due to their unique properties in different field of science. In this letter, after final optimization, thermodynamic properties analysis, stabilities, electronic structure and nuclear magnetic resonance parameters including σ isotropic and σ anisotropic tensors and asymmetric parameters of 15N and 11B nuclei are calculated....
