Unusual temperature dependence of the oxygen-isotope effect on the exchange-energy of $L a_{1 - x} C a_{x} M n O_{3}$ at high temperatures

Guo-meng Zhao, John Mann

We report magnetic susceptibility $χ (T)$ measurements on oxygen-isotope exchanged La $_{1 - x}$ Ca $_{x}$ MnO $_{3 + y}$ up to 700 K. The $1/ χ (T)$ data show that the ferromagnetic exchange-…

Large oxygen-isotope shift above the quantum critical point of $Y_{1 - x} C a_{x} B a_{2} C u_{3} O_{7 - d e l t a}$

John Mann, Pieder Beeli, Guo-meng Zhao

We have studied the oxygen-isotope effect on the superconducting transition temperature $T_{c}$ in overdoped Y $_{1 - x}$ Ca $_{x}$ Ba $_{2}$ Cu $_{3}$ O $_{7 - δ}$ with $x$ = 0.10, 0.20, and 0…
