Hyperfine transition induced by atomic motion above a paraffin-coated magnetic film
Naota Sekiguchi, Hiroaki Usui, Atsushi Hatakeyama
We measured transitions between the hyperfine levels of the electronic ground state of potassium-39 atoms (transition frequency: 460 MHz) as the atoms moved through a periodic magn…
Spin-dependent metastable He () atom scattering from ferromagnetic surfaces: Potential application to polarized-gas production
Haruka Maruyama, Mitsunori Kurahashi, Kanta Asakawa +1
A spin-polarized triplet metastable helium (He*) beam has been used as a probe for surface magnetism, but changes in the spin state during scattering from a surface remain unclear.…
Magnetism of AlFeGeO with Andalusite Structure
K. Kakimoto, S. Takada, H. Ohta +8
The magnetism of AlFeGeO from = 0.09 to = 0.91 with andalusite structure was examined. The magnetic properties of AlFeGeO at low temperature…
Measurement of the temperature dependence of dwell time and spin relaxation probability of Rb atoms on paraffin surfaces using a beam-scattering method
Kanta Asakawa, Yutaro Tanaka, Kenta Uemura +5
The scattering of Rb atoms on an anti-relaxation coating was studied. No significant change in the spin relaxation probability of Rb atoms by single scattering from a tetracontane…
Systematic studies of rubidium-exposed surfaces by X-ray photoelectron spectroscopy and light-induced atom desorption
Atsushi Hatakeyama, Sae Watashima, Ayumi Yamaguchi +6
We systematically investigated various types of surfaces on which rubidium (Rb) atoms were deposited by X-ray photoelectron spectroscopy (XPS) and measured the light-induced atom d…
Characterization of a double torsion pendulum used to detect spin-induced torque based on Beth's experiment
Runa Yasuda, Atsushi Hatakeyama
We characterized a double torsion pendulum system, including measurements of the photon-spin-induced torque. Our experimental strategy was similar to that used in Beth's experiment…
