We have investigated structural and electrical properties of "ribbon-knot" crystals of TaSe3 (superconductor) having nontrivial topological structures. They are shaped a ring, a Mobius strip and a 2pi-twisted loop, so they can be categorized by a ribbon knot topological invariant in the mathematics field. For investigation of structural property of the ring crystals, cutting operation was performed for 45 specimens of the TaSe3 ring crystal using focused ion beam milling. The cutting operation transformed them to arc-shape crystals having homogeneous curvatures. At low temperature, thin ring crystals of TaSe3 showed superconductivity, however, thick rings showed nonmetallic behavior. The experimental results suggest that the ring-shape structure affect the electrical behavior in the TaSe3 ring crystal. (C) 2003 Elsevier Science B.V. All rights reserved.
