| Research Abstract |
We have succeeded in developing a simple experimental technique for detecting the orientation of vortex lattice in the flux-flow state for type II superconductors. This technique is based on the resonance between the periodicity in vortex-lattice motion and a small rf current superimposed on top of the transport current. It is applicable to the small samples including films which are not possible to study by the conventional method of the small angled neutron scattering measurement. Employing the resonant technique to amorphous superconducting films, we find not only the lattice orientation parallel to the flow direction, but also the perpendicular orientation which is not expected in theoretical studies so far.
