Reentrant superconductivity in YBa${}_2$Cu${}_3$O${}_{7-d}$ microstructured particles

Rodolfo E. López-Romero, Dulce Y. Medina, R. Escudero

A reentrant superconducting effect was observed in YBCO particles as a consequence of their size and microstructure. It rises from the coexistence between bulk superconductivity an…
