Abstract
151Eu Mössbauer studies have been made across the respective superconductive transition temperatures in two compounds, La1.7Eu0.1Sr0.2CuO4−y and EuBa2Cu3O7, having zero resistance state at 25K and 85K respectively. The 151Eu isomer shift data establish that Eu ions are in trivalent state at all temperatures. The Mössbauer f-factor does not show any significant anomaly across the Tc.
