Negative nonlocal and local voltages (resistances) in a quasi-one-dimensional superconducting aluminum structure

•We measured negative nonlocal and local dc voltages in a superconducting structure.•The structure consists of narrow and wide wires with critical temperatures Tn and Tw.•We found negative nonlocal and local voltages (resistances) at temperatures Tn
