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…
Independent determination of the two gaps by directional point-contact spectroscopy in MgB_2 single crystals
R. S. Gonnelli, D. Daghero, G. A. Ummarino +4
Directional point-contact spectroscopy measurements were performed for the first time in state-of-the-art MgB_2 single crystals. The selective suppression of the superconductivity…
Observation of vortex structure in MgB single crystals by Bitter decoration technique
L. Ya. Vinnikov, J. Karpinski, S. M. Kazakov +4
We report the observation of superconducting vortices in pure and lightly Al doped MgB single crystals. Low field experiments allow for the estimation of the London penetration…
Scanning Tunneling Spectroscopy on Single Crystal MgB2
M. R. Eskildsen, M. Kugler, G. Levy +5
We report on the results of scanning tunneling spectroscopy measurements on single crystals of Mg2. Tunneling was performed both parallel and perpendicular to the crystalline c-axi…
Vortex Imaging in the pi-Band of Magnesium Diboride
M. R. Eskildsen, M. Kugler, S. Tanaka +4
We report scanning tunneling spectroscopy imaging of the vortex lattice in single crystalline MgB2. By tunneling parallel to the c-axis, a single superconducting gap (Delta = 2.2 m…
