Keller A negative oxygen-isotope ( O 16 / O 18 ) effect (OIE) on the low-temperature tetragonal (LTT) phase-transition temperature T LTT was observed in La 2 − x Ba x CuO 4 ( x = 1 / 8 ) using high-resolution neutron powder diffraction. The corresponding OIE exponent α T LTT = − 0.36 ( 5 ) has the same sign as α T so = − 0.57 ( 6 ) found for … [Phys. Rev. B 92, 024508] Published Mon Jul 13, 2015
