Effects of the pseudo-gap on the field-induced kinetic energy density of BiSrCaCuO single crystals
Lutiene F. Lopes, Jully P. Peña, Milton A. Tumelero +3
We report on magnetization experiments from which we obtain the field-induced kinetic energy density, , in the superconducting phase of several BiSrCaCuO s…

The chiral Anomalous Hall effect in re-entrant AuFe alloys
F. Wolff Fabris, P. Pureur, J. Schaf +2
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 linke…
Experimental observation of two-dimensional fluctuation magnetization in the vicinity of T_c for low values of the magnetic field in deoxygenated YBa_2Cu_3O_{7-x}
S. Salem-Sugui, A. D. Alvarenga, V. N. Vieira +1
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…
A comparative study of high-field diamagnetic fluctuations in deoxygenated YBa2Cu3O(7-x) and polycrystalline (Bi-Pb)2Sr2Ca3O(10)
S. Salem-Sugui, A. D. Alvarenga, K. C. Goretta +3
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 wer…
