Application d'une methodologie RPE a sonde de spin a la mesure de la profondeur de penetration magnetique λ pour les deux supraconducteurs.Abstract:
Using a newly devleoped EPR spin-probing methodology, we have measured magnetic penetration depth {lambda} for Tl{sub 2}Ba{sub 2}Ca{sub 2}Cu{sub 3}O{sub {ital x}} and Bi{sub 2}Ca{sub 2}SrCu{sub 2}O{sub {ital x}}. The temperature dependence of {lambda} is found to follow the relationship {lambda}={lambda}{sub 0}(1{minus}(T/T{sub {ital c}}){sup 4}){sup {minus}1/2}, with {lambda}{sub 0}=2520{plus minus}100 A and {ital T}{sub {ital c}}=119 K for Tl{sub 2}BaCa{sub 3}Cu{sub 3}O{sub 7.8+{ital x}} and {lambda}{sub 0}=2700{plus minus}100 A with {ital T}{sub {ital c}}=84 K for Bi{sub 2}Ca{sub 2}SrCu{sub 2}O{sub {ital x}}.read more

Numerical simulations on two dimensional vortex lattices
D. Reefman,H. B. Brom +1 more
TL;DR: In this paper, the dynamics of a two-dimensional vortex lattice with the use of a molecular dynamics method for systems of up to 2000 vortices was studied and the interaction potential was taken to be of the Pearl form and temperature was taken into account via a white Gaussian noise source.

Magnetic flux inhomogeneity in ceramic YBa2Cu3O7−δ superconductors studied by EPR
TL;DR: In this paper, local magnetic flux density on the surface of a ceramic YBa2Cu3O7−δ sample was measured by electron paramagnetic resonance (EPR) probes, and it was shown that the inhomogeneity of the flux is due primarily to the granular nature of the sample, rather than to the flux lattice.
