Spin polarization of (Ga,Mn)As measured by Andreev Spectroscopy: The role of spin-active scattering
S. Piano, R. Grein, C. J. Mellor +5
We investigate the spin-polarization of the ferromagnetic semiconductor (Ga,Mn)As by point contact Andreev reflection spectroscopy. The conductance spectra are analyzed using a rec…
Electrical and magnetic properties of nano-scale Pi-junctions
Samanta Piano
The physics of the "Pi" phase shift in ferromagnetic Josephson junctions enables a range of applications for spin-electronic devices and quantum computing. In this respect our rese…
0-pi oscillations in nanostructured Nb/Fe/Nb Josephson junctions
Samanta Piano, J. W. A. Robinson, G. Burnell +1
The physics of the phase shift in ferromagnetic Josephson junctions may enable a range of applications for spin-electronic devices and quantum computing. We investigate transit…
Critical Current Oscillations in Strong Ferromagnetic Pi-Junctions
J. W. A. Robinson, S. Piano, G. Burnell +2
We report magnetic and electrical measurements of Nb Josephson junctions with strongly ferromagnetic barriers of Co, Ni and Ni80Fe20 (Py). All these materials show multiple oscilla…
