Abstract
Resistivity, magnetisation, and specific heat measurements on the new layered superconductors Y2C2Br2 and Y2C2I2 have been performed to char acterise their superconducting state. An analysis of the specific heat anomalies at T-c in terms of the two-fluid (2fl) model and McMillan's coupling parameter reveal electron phonon coupling in the moderately strong regime. Indication for strong coupling is also rendered from an analysis of the magnetisation data by means of the alpha-model.
