Anisotropy of the antiferromagnetic spin correlations in the superconducting state of YBa_2Cu_3O_7 and YBa_2Cu_4O_8
A. Uldry, M. Mali, J. Roos +1
We present evidence that the antiferromagnetic spin correlations in optimally doped YBa_2Cu_3O_7 and underdoped YBa_2Cu_4O_8 develop a surprisingly strong anisotropy in the superco…

Direct observation of the oxygen isotope effect on the in-plane magnetic field penetration depth in optimally doped YBaCuO
R. Khasanov, D. G. Eshchenko, H. Luetkens +8
We report the first direct observation of the oxygen-isotope (O/O) effect on the in-plane penetration depth in a nearly optimally doped YBaCuO$_{7-δ}…
