Improving HTc Josephson Junctions (HTc JJ) by annealing: the role of vacancy-interstitial annihilation
M. Sirena, S. Matzen, N. Bergeal +4
We have studied the annealing effect in transport properties of High temperature Josephson Junctions (HTc JJ) made by ion irradiation. Low temperature annealing (80 degrees Celsius…
Study and optimization of ion-irradiated High-Tc Josephson nanoJunctions by Monte Carlo simulations
M. Sirena, N. Bergeal, J. Lesueur +5
High Tc Josephson nanoJunctions (HTc JnJ) made by ion irradiation have remarkable properties for technological applications. However, the spread in their electrical characteristics…
Combining half-metals and multiferroics into epitaxial heterostructures for spintronics
H. Bea, M. Bibes, M. Sirena +8
We report on the growth of epitaxial bilayers of the La2/3Sr1/3MnO3 (LSMO) half-metallic ferromagnet and the BiFeO3 (BFO) multiferroic, on SrTiO3(001) by pulsed laser deposition. T…
Antiferromagnetism at the YBa2Cu3O7 / La2/3Ca1/3MnO3 interface
N. Haberkorn, J. Guimpel, M. Sirena +4
The magnetic properties of a series of YBa2Cu3O7-x/La2/3Ca1/3MnO3 (YBCO/LC1/3MO) superlattices grown by dc sputtering at high oxygen pressures (3.5 mbar) show the expected ferromag…
