Recent investigations have shown that the first proposed explanations of the disagreement between experimental and theoretical value of isotope coefficient in MgB2 need to be reconsidered. Considering that in samples with residual…
The Meissner effect is one of the defining properties of superconductivity, with a conventional superconductor completely repelling an external magnetic field. In contrast to this diamagnetic behavior, odd-frequency superconducting pairing…

This paper was withdrawn by the author. It turns out that similar ideas have been presented before. The author apologizes.
This paper has been withdrawn for extensive revision.
Using the non-linear Ginzburg-Landau (GL) theory, we study the magnetic response of different shaped samples in the field-cooled regime (FC). For high external magnetic fluxes, the conventional diamagnetic response under cooling down can be…
This paper has been withdrawn, as it should not have been a new submission. Please instead see the latest version of arXiv:0904.0436.
This paper has been withdrawn by the author, due to a misunderstanding about publication.
Paper withdrawn because of unjustified approximation between equations 13 and 14.
This paper has been withdrawn by the authors due to errors in the X-ray diffraction data. Other measured data are not affected; however, the errors significantly change the interpretation and conclusions, and thus warrant withdrawal and…
This paper has been withdrawn by the author. It will be posted on astro-ph once the proceedings of the 363rd Heraeus Seminar on Neutron Stars and Pulsars are ready.
This paper has been withdrawn by the author due to a coming paper completely superseding it.
This paper has been withdrawn by the author due to a some errors in figures 2 and 3.
The paper has been withdrawn by the author, due to it being fundamentally flawed. The author apologizes for any inconvenience it may have caused.
Over the past 14 years MgB2 has gone from a startling discovery to a promising, applied superconductor. In this article we present a brief overview of the synthesis and the basic superconducting properties of this remarkable compound. In…
The paper is withdrawn. The proof has an error and it requires a different approach.
We have imaged the spatial distribution of magnetic flux on a granular sample of the high-temperature superconductor Bi2Sr2CaCu2Ox using a scanning SQUID microscope. Our results establish the presence of spontaneous orbital magnetic moments…
This paper has been withdrawn by the authors as the available data were not sufficient to support the conclusions
