Thermal expansion of LaBa2Cu2CoO7+δ

In this paper, we report high-temperature X-ray diffraction (HTXRD) and dilatometric studies on LaBa2Cu2CoO7+δ. Bulk and volume thermal expansion studies, along with a study of its phase transition, were carried out. The linear and volume thermal expansion coefficients were found to be 11.7 × 10−6 K−1 and 42.3 × 10−6 K−1, respectively.
