Abstract

Magnetic trapping and optical manipulation of micro-particles are combined in superfluid helium. Irradiation of pulsed light to a magnetically trapped superconducting particle causes simple damped oscillation of the particle. The analysis of the trajectory gives rise to the estimation of viscosity of the superfluid helium along with some properties of the trapped particle.
