Strong coupling between Eu2+ spins and Fe2As2 layers in EuFe1.9Co0.1As2 observed with NMR

Z. Guguchia, J. Roos, A. Shengelaya +8

A combination of x-ray diffraction, magnetization, and 75As nuclear magnetic resonance (NMR) experiments were performed on single-crystal EuFe1.9Co0.1As2. The strength of the hyper…

Anisotropy of superconducting single crystal SmFeAsO_(0.8)F_(0.2) studied by torque magnetometry

S. Weyeneth, R. Puzniak, U. Mosele +7

Single crystals of the oxypnictide superconductor SmFeAsO_(0.8)F_(0.2) with T_c=45(1) K were investigated by torque magnetometry. The crystals of mass~0.1 mug were grown by a high-…

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…

Absence of a boron isotope effect in the magnetic penetration depth of MgB

D. Di Castro, M. Angst, D. G. Eshchenko +11

The magnetic penetration depth in polycrystalline MgB for different boron isotopes (B/B) was investigated by transverse field muon spin rotation. No boro…

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}…

Anisotropy of the superconducting state properties and phase diagram of MgB2 by torque magnetometry on single crystals

M. Angst, R. Puzniak, A. Wisniewski +6

The angular and temperature dependence of the upper critical field Hc2 in MgB2 was determined from torque magnetometry measurements on single crystals. The Hc2 anisotropy gamma_H w…
