Searching for Magnetostatic Modes in Spin-Polarized Atomic Hydrogen
Lauri Lehtonen, Otto Vainio, Janne Ahokas +4
We consider a possibility of the magnetostatic type spin waves driven by a long-range magnetic dipole interactions, to account for the peaks in the ESR spectra observed in our prev…
Spin Waves in Quantum Gases --- The Quality Factor of the Identical Spin Rotation Effect
L. Lehtonen, O. Vainio, J. Ahokas +6
Our recent experimental work on electron spin waves in atomic hydrogen gas has prompted a revisit of the theory of the Identical Spin Rotation Effect (ISRE). A key characteristic d…
Dynamic Polarization and Relaxation of 75As Nuclei in Silicon at High Magnetic Field and Low Temperature
J. Järvinen, J. Ahokas, S. Sheludyakov +5
We present the results of experiments on dynamic nuclear polarization and relaxation of 75As in silicon crystals. Experiments are performed in strong magnetic fields of 4.6 T and t…
Dynamic nuclear polarization and relaxation of H and D atoms in solid mixtures of hydrogen isotopes
S. Sheludiakov, J. Ahokas, J. Järvinen +5
We report on a study of Dynamic Nuclear Polarization and electron and nuclear spin relaxation of atomic hydrogen and deuterium in solid molecular matrices of H, D, and…
ESR study of atomic hydrogen and tritium in solid T and T:H matrices below 1K
S. Sheludiakov, J. Ahokas, J. Järvinen +6
We report on the first ESR study of atomic hydrogen and tritium stabilized in a solid T and T:H matrices down to 70mK. The concentrations of T atoms in pure T…
Identical Spin Rotation Effect and Electron Spin Waves in Quantum Gas of Atomic Hydrogen
L. Lehtonen, O. Vainio, J. Ahokas +7
We present an experimental study of electron spin waves in atomic hydrogen gas compressed to high densities of cm at temperatures ranging from 0.26 t…
