Abstract

The structure parameters of (La,_jrCaje)2Cu04 (∗=0.05) with the K2NiF4-type structure were refined by Rietveld analysis of time-of-flight neutron powder diffraction data. This superconductor with a Tc of 24 K is orthorhombic at both room temperature and 18 K. From experimental results obtained by us and Fukuoka et al., we conclude that the relatively low Tc value for the superconductor is due to a low concentration of hole carriers introduced by Ca doping.
