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…

Magnetism and superconductivity in Ru(1-x)Sr2RECu(2+x)O(8-d) (RE=Gd, Eu) and RuSr2Gd(1-y)Ce(y)Cu2O8 compounds

P. W. Klamut, B. Dabrowski, S. M. Mini +13

We discuss the properties of new superconducting compositions of Ru(1-x)Sr2RECu(2+x)O(8-d) (RE=Gd, Eu) ruthenocuprates that were synthesized at 600 atm. of oxygen at 1080 C. By cha…

MgB2 single crystals: high pressure growth and anisotropic properties

J. Karpinski, M. Angst, J. Jun +11

Single crystals of MgB2 with a size up to 1.5x0.9x0.2 mm3 have been grown with a high pressure cubic anvil technique. The crystal growth process is very peculiar and involves an in…

Comment on "Superconducting anisotropy and evidence for intrinsic pinning in single crystalline MgB2"

M. Angst, R. Puzniak, A. Wisniewski +3

In a recent paper [Phys. Rev. B 66, 012501 (2002)], torque data measured on a MgB2 single crystal in fields from 10 to 60 kOe at 10 K were presented. The authors obtained the aniso…

Disorder-induced Phase Transition of Vortex Matter in MgB2

M. Angst, R. Puzniak, A. Wisniewski +3

Measurements of single crystalline MgB2 with torque magnetometry in fields up to 90 kOe reveal a sharp peak in the irreversible torque at about 0.85 Hc2. In the region between peak…

Mixed state properties of superconducting MgB2 single crystals

M. Zehetmayer, M. Eisterer, H. W. Weber +4

We report on measurements of the magnetic moment in superconducting MgB2 single crystals. We find μ_0H_{c2}^c(0) = 3.2 T, μ_0H_{c2}^{ab}(0) = 14.5 T, γ= 4.6, μ_0H_c(0) = 0.28 T, an…
