Abstract

The structure parameters of (La1-xCax) 2CuO4 (x=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 T c value for the superconductor is due to a low concentration of hole carriers introduced by Ca doping.
