We have obtained isofield curves for the square root of the average kinetic energy density of the superconducting state for three single crystals of underdoped YBa_2Cu_3O_{7-x}, an optimally doped...
The Anomalous Hall effect in re-entrant AuFe alloys and the real space Berry phase (2007)
Pureur, P., Fabris, F. Wolff, Schaf, J., Vieira, V. N., Campbell, I. A.
The Hall effect has been studied in a series of AuFe samples in the re-entrant concentration range, as well as in the spin glass range. The data demonstrate that the degree of canting of the local...
The chiral Anomalous Hall effect in re-entrant AuFe alloys (2006)
Fabris, F. Wolff, Pureur, P., Schaf, J., Vieira, V. N., Campbell, I. A.
The Hall effect has been studied in a series of AuFe samples in the re-entrant concentration range, as well as in part of the spin glass range. An anomalous Hall contribution linked to the tilting of...

We measured isofield magnetization curves as a function of temperature in two single crystal of deoxygenated YBaCuO with T_c = 52 and 41.5 K. Isofield MvsT were obtained for fields running from 0.05...

We studied three single crystals of YBa2Cu3O{7-x} with Tc= 62.5, 52, and 41 K, and a textured specimen of (Bi-Pb)2Sr2Ca2Cu3O10 with Tc=108 K, for H//c axis. The reversible data were interpreted in...
