Transport properties of microstructured ultrathin films of La0.67Ca0.33MnO3 on SrTiO3 (2007)
Beekman, C., Komissarov, I., Hesselberth, M., Aarts, J.
We have investigated the electrical transport properties of 8 nm thick La0.67Ca0.33MnO3 films, sputter-deposited on SrTiO3 (STO), and etched into 5 micrometer-wide bridges by Ar-ion etching. We find...
Long-range nonlocal flow of vortices in narrow superconducting channels (2004)
Grigorieva, I. V., Geim, A. K., Dubonos, S. V., Novoselov, K. S., Vodolazov, D. Y., Peeters, F. M., ...
We report a new nonlocal effect in vortex matter, where an electric current confined to a small region of a long and sufficiently narrow superconducting wire causes vortex flow at distances hundreds...
Rusanov, A. Yu., Hesselberth, M., Aarts, J., Buzdin, A. I.
In (S/F) hybrids the suppression of superconductivity by the exchange field h_ex of the ferromagnet can be partially lifted when different directions of h_ex are sampled simultaneously by the Cooper...
Depairing currents in superconductor / ferromagnet Nb/CuNi trilayers close to T$_c$ (2003)
Rusanov, A., Hesselberth, M., Habraken, S., Aarts, J.
In superconductor/ferromagnet (S/F) heterostructures, the exchange field $h_{ex}$ of the F-layer suppresses the superconducting order parameter in the S-layer via the proximity effect. One issue in...
Inhomogeneous superconductivity induced in a weak ferromagnet (2001)
Rusanov, A., Boogaard, R., Hesselberth, M., Sellier, H., Aarts, J.
Under certain conditions, the order parameter induced by a superconductor (S) in a ferromagnet (F) can be inhomogeneous and oscillating, which results e.g. in the so-called pi-coupling in S/F/S...
