Resistance anomalies and negative magnetoresistance in a regular 3D lattice of superconducting nanostructures
Regular 3D lattices of superconducting nanostructures of the variable-thickness-bridge type have been prepared by using indium to fill voids in a crystallographically ordered insulating matrix. The matrix was modified by molecular lamination of Ti02 on its interior surface. The R(T9H) dependence was measured. The R(T) curve exhibits two successive resistance anomalies as the temperature is lowered. These anomalies are associated with a negative behavior of the magnetoresistance.
