139La NMR evidence for phase solitons in the ground state of overdoped manganites
D. Koumoulis, N. Panopoulos, A. Reyes +6
Hole doped transition metal oxides are famous due to their extraordinary charge transport properties, such as high temperature superconductivity (cuprates) and colossal magnetoresi…
Spin order and lattice frustration in optimally doped manganites. A high temperature NMR study.
N. Panopoulos, D. Koumoulis, G. Diamantopoulos +4
The physics underlying the complex glassy phenomena, which accompany the formation of polarons in optimally doped manganites (ODM) is a cumbersome issue with many unexplained aspec…
Synergy of exchange bias with superconductivity in ferromagnetic-superconducting layered hybrids: the influence of in-plane and out-of-plane magnetic order on superconductivity
D. Stamopoulos, E. Manios, M. Pissas
It is generally believed that superconductivity and magnetism are two antagonistic long-range phenomena. However, as it was preliminarily highlighted in D. Stamopoulos et al. [Phys…
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…
Manipulating superconductivity through the domain structure of a ferromagnet: experimental aspects and theoretical implications
D. Stamopoulos, M. Pissas
In the present work we study experimentally the influence that the domain structure of a fer- romagnet (FM) has on the properties of a superconductor (SC) in bilayers and multilaye…
