Description
The layered carbide bromide La2C2Br2 becomes superconducting at 6.2 K. We studied the matrix effect on Tc due to (isoelectronic) halogen substitution. Tc increases with the amount of substitution by chlorine to a maximum value of 7.2 K, and it decreases when Br- is partially substituted by I-. La2C2I2 itself is non-superconducting down to 2 K. However, substitution of I- by 10% Cl- leads to superconductivity at 2.2 K. (orig.)
