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