Autor: Dick Veldhuis, Hans Hilgenkamp, Dave H.A. Blank, F.J.G. Roesthuis, I. Oomen, D. Mijatovic, Horst Rogalla, Guus Rijnders, Alexander Brinkman

Publikováno v: Superconductor science and technology, 16(2), 246-253. IOP Publishing Ltd.

The remarkably high critical temperature at which magnesium diboride (MgB2) undergoes transition to the superconducting state, Tc approx 40 K, has aroused great interest and has encouraged many groups to explore the properties and application potenti

Pulsed laser ablation of La0.5Sr0.5CoO3

Autor: Dave H. A. Blank, F.J.G. Roesthuis, Horst Rogalla, E.A.F. Span

Publikováno v: Applied Surface Science. 150:171-177

The ablation process of La0.5Sr0.5CoO3 by a spatial uniform 248 nm excimer laser beam has been characterized. Ablation rates, changes in the target surface morphology and composition have been studied as a function of the laser fluence. The dependenc

Magnetic relaxation in Barium ferrite films with perpendicular anisotropy

Autor: F.J.G. Roesthuis, A. Lisfi, J.C. Lodder, P. de Haan, Thijs Bolhuis

Publikováno v: Journal of magnetism and magnetic materials, 193(1-3), 258-261. Elsevier

Magnetic relaxation analysis have been carried out on barium ferrite films with perpendicular anisotropy, grown by pulsed laser deposition. Logarithmic behaviour on the time dependence of the magnetisation has been observed. The measured and correcte

Quasiparticle injection effects in YBa2Cu3Ox-based planar structures at high operating temperatures

Autor: Horst Rogalla, A. G. Sivakov, F.J.G. Roesthuis, G.J. Gerritsma, Y.M. Boguslavskij, K. Joosse

Publikováno v: Physica C, 220(1-2), 195-202. Elsevier

The modulation of the supercurrent Is of a YBCO bridge by the quasiparticle-injection current IG from the YBCO/Au or YBCO/PBCO/Au junctions at temperatures of 60–85 K is determined by two effects: (1) summation of the currents IS and IG in the YBCO

Fabrication aspects of microwave devices, including ramp-type high-Tc Josephson junctions and log-periodic antennas

Autor: D. Terpstra, Augustinus J.H.M. Rijnders, David H.A. Blank, Horst Rogalla, G.J. Gerritsma, F.J.G. Roesthuis

Publikováno v: Journal of alloys and compounds, 195, 719-722. Elsevier

We describe the development of high-Tc Josephson junction devices for applications at millimeter wave frequencies. These devices consist of ramp type YBCO/PBCO/YBCO Josephson junctions that are equipped with a noble metal log-periodic antenna. Growth

Barium ferrite films grown by laser ablation

Autor: M.A. Smithers, A. Lisfi, F.J.G. Roesthuis, J.C. Lodder, P. de Haan

Publikováno v: IEEE transactions on magnetics, 34(4), 159-162. IEEE

Pulsed laser ablation (PLA) has been used to grow barium ferrite films on Al/sub 2/O/sub 3/ single crystal substrates. When deposition occurs in an oxidising atmosphere at high temperatures, the films are single BaFe/sub 12/O/sub 19/ phase, very well
