Dynamic nuclear polarization and ESR hole burning in As doped silicon
J. Jarvinen, D. Zvezdov, J. Ahokas +6
We present an experimental study of the Dynamic Nuclear Polarization (DNP) of \si{} nuclei in silicon crystals of natural abundance doped with As in the temperature range 0.1-1 K a…
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…
Bose-Einstein condensation of magnons in atomic hydrogen gas
O. Vainio, J. Ahokas, J. Järvinen +8
We report on experimental observation of BEC-like behaviour of quantized electron spin waves (magnons) in a dense gas of spin polarized atomic hydrogen. The magnons are trapped and…
