Description
Summary:•Three-dimensional periodic superconducting structures demonstrate diverse pinning mechanisms.•For carcasses consisted of octahedral and tetrahedral tin nanoparticles with the diameter of 128 and 70 are found to be a type-I superconductor.•The tin sample formed by 80 and 42 nm particles demonstrates an analog of intertype superconductivity: features of both type-I and II superconductors are observed on the magnetization isothermal curves. Magnetization hysteresis loops of tin samples with an inverted opal structure are presented. The sample formed by tin particles with the size of 70 and 128 nm is found to be a type-I superconductor. The tin sample formed by 80 and 42 nm particles demonstrates an analog of intertype superconductivity: features of both type-I and II superconductors are observed on the magnetization isothermal curves. A behavior of the irreversible and reversible magnetizations supports coexistence of type-I and II superconducting nanoparticles in this sample.
