Superconducting phase formation in random neck syntheses: a study of the Y-Ba-Cu-O system by magneto-optics and magnetometry
J. B. Willems, J. Albrecht, I. L. Landau +1
Magneto-optical imaging and magnetization measurements were applied to investigate local formation of superconducting phase effected by a random neck synthesis in Y-Ba-Cu-O system.…
Comparison of the scaling analysis of the mixed-state magnetization data with direct measurements of the upper critical field in Y-123
I. L. Landau
By comparison of recent direct measurements of the temperature dependence of the upper critical field in an Y-123 high temperature superconductor with the scaling analysis…
Detailed magnetization study of superconducting properties of YBCO ceramic spheres
I. L. Landau, J. B. Willems, J. Hulliger
We present a magnetization study of low density YBCO ceramics carried out in magnetic fields 0.5 Oe < H < 50 kOe. It was demonstrated that superconducting links between grains may…
On the interpretation of muon-spin-rotation experiments in the mixed state of type-II superconductors
I. L. Landau, H. Keller
We argue that claims about magnetic field dependence of the magnetic field penetration depth lambda, which were made on the basis of moun-spin-rotation studies of some superconduct…
Two types of Hc2(T) dependences in Bi_2Sr_2Ca_(1-x)Y_xCu_2O_(8+delta) with different Yttrium content
I. L. Landau, H. Keller
We reanalyze the magnetization data collected on Bi_2Sr_2Ca_(1-x)Y_xCu_2O_(8+y) samples (Kim at al, Phys. Rev. B 72, 64525 (2005)) and argue that the method, which was used for the…
Muon-spin-rotation measurements of the penetration depth in Li_2Pd_3B
R. Khasanov, I. L. Landau, C. Baines +4
Measurements of the magnetic field penetration depth in the ternary boride superconductor LiPdB ( K) have been carried out by means of muon-spin rotation…
