Abstract :
Direct observation of vortex arrangement in microscopic superconductors is achieved with a scanning SQUID microscope. Newly 2 μm diameter sensing pickup coil is developed for the observation of giant vortex state. Vortex arrangements in 10 μm triangles is investigated with the new pickup device. No giant vortex state, however, can be seen under this experimental condition. Further investigation is needed.
