Abstract

The effect of substitution of Sr for a part of Ba in superconducting GdBa2Cu4O8and HoBa2Cu4O8on critical temperatures and lattice constants was investigated. The critical temperatures were definitely unchanged in spite of the reduction of the unit cell which was reportedly effective for the enhancement of the critical temperature in the rare-earth element substitution. The ortho-rhombicities of unit cells increased with the Sr content, as resulted from the large shortening of theaaxis compared with thebaxis. In the present work, the dependence of the shortening of each axis on the ionic radius of a rare-earth element was found.
