Effective gap at microwave frequencies in MgB2 thin films with strong interband scattering

G. Ghigo, D. Botta, A. Chiodoni +6

The microwave properties of polycrystalline MgB2 thin films prepared by the so-called in-situ method are investigated. The characterization of the films at microwave frequencies wa…

A new apparatus for deep patterning of beam sensitive targets by means of high-energy ion beam

A. Rovelli, A. Amato, D. Botta +7

The paper reports on a high precision equipment designed to modify over 3-dimensions (3D) by means of high-energy gold ions the local properties of thin and thick films. A target-m…

Geometry dependent distribution of the supercurrent in YBa2Cu3O7-x films with patterned pinning landscape

F. Laviano, D. Botta, A. Chiodoni +5

We created local pinning modulations in YBCO films by means of confined high energy heavy ion irradiation. The high energy of the ions allows us to introduce nanometric size defect…

Evidences of vortex curvature and anisotropic pinning in superconducting films by quantitative magneto-optics

F. Laviano, D. Botta, A. Chiodoni +5

We present the experimental observation of magnetic field line curvature at the surface of a superconducting film by local quantitative magneto-optics. In addition to the knowledge…

Critical state analysis in MgB2 bulk by means of quantitative MO technique

L. Gozzelino, F. Laviano, D. Botta +8

An extended magneto-optical (MO) analysis of samples cut from high-density pellets of MgB2 is reported. For sake of comparison some magnetic measurements and critical values are al…
