Abstract

The origins of the anisotropic physical properties of CePtAs and LaPtAs were investigated by the optical conductivity and the XPS measurements. Optical conductivity spectra indicate that the property parallel to the c-axis is semiconducting and that perpendicular to the c-axis is metallic both for CePtAs and LaPtAs. The spectral features due to the p-f mixing also show the anisotropic nature of CePtAs, namely, the intensity perpendicular to c-axis is stronger than that along c-axis.
