Abstract
The amplitudes of Shapiro steps are measured at temperatures up to 77 K for a superconductor‐normal metal‐superconductor Josephson weak link fabricated from YBa2Cu3O7−δ with a Ag‐Au alloy bridge. The step amplitudes are found to be in agreement with calculations based on the resistively shunted‐junction model when the Johnson noise of the junction resistance is included.Keywords
