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…
