Stray-fields-based magnetoresistance mechanism in Ni80Fe20-Nb-Ni80Fe20 trilayers
D. Stamopoulos, E. Manios, M. Pissas
We report on the transport and magnetic properties of hybrid trilayers and bilayers that consist of low spin-polarized Ni80Fe20 exhibiting in-plane but no uniaxial anisotropy and l…
Enhancement of Superconductivity by Exchange Bias
D. Stamopoulos, E. Manios, M. Pissas
In this work we study the transport properties of hybrids that consist of exchange biased ferromagnets (FMs) combined with a low-Tc superconductor (SC). Not only different FMs but…
Mössbauer study of NaCoO (doped by 1% Fe)
M. Pissas, V. Psycharis, D. Stamopoulos +3
We studied by Mössbauer spectroscopy the NaCoO compound using 1% Fe as a local probe which substitutes for the Co ions. Mössbauer spectra at T=300 K revealed tw…
Influence of carbon doping in the vortex matter properties of MgB
M. Pissas, D. Stamopoulos, S. Lee +1
We have studied the vortex-matter phase diagram of low C doped MgB superconductor. The significant finding is the appearance of a peak effect, which, as both our global magneti…
Surface barrier and bulk pinning in MgB superconductor
M. Pissas, E. Moraitakis, D. Stamopoulos +3
We present a modified method of preparation of the new superconductor MgB. The polycrystalline samples were characterized using x-ray and magnetic measurements. The surface bar…
