“…For the purely orbital (electromagnetic) mechanism of the superconductivity destruction, the nucleation of the superconductivity in the presence of domain structure has been theoretically studied in 4,5 for the case of magnetic film with perpendicular anisotropy. The conditions of the superconductivity appearance occur to be more favorable near the domain walls due to the partial compensation of the magnetic induction.…”

We analyze the enhancement of the superconducting critical temperature of superconducting/ferromagnetic bilayers due to the appearance of localized superconducting states in the vicinity of magnetic domain walls in the ferromagnet. We consider the case when the main mechanism of the superconductivity destruction via the proximity effect is the exchange field. We demonstrate that the influence of the domain walls on the superconducting properties of the bilayer may be quite strong if the domain wall thickness is of the order of superconducting coherence length.

“…2(a), magnetic domains can be considered within the small size regime, with no reentrant effects in the hybrid FM/SC system, as long as K/2 < 1.8L H . 22 This condition is fulfilled in the whole studied thickness range of the Nd-Co/Nb bilayers, as shown in Fig. 2(b), indicating that all the samples in this work can be considered within the small domain size regime.…”

“…10 In hybrid SC/FM bilayers, the comparison between L H and the size of each stripe domain K/2 determines the overlapping between the superconducting nuclei above each magnetic domain and the presence or not of reentrant superconductivity phase diagrams. 22 In particular, for sinusoidal stray field variations, similar to the H z stray (x) profiles in the inset of Fig. 2(a), magnetic domains can be considered within the small size regime, with no reentrant effects in the hybrid FM/SC system, as long as K/2 < 1.8L H .…”

Magnetization reversal processes have been studied in hybrid magnetic/superconducting Nd-Co/Nb bilayers by the comparison of out-of-plane magnetic hysteresis loops and superconducting phase diagrams as a function of magnetic layer thickness and of disorder in the magnetic layer induced by a nanostructured copolymer template. A good correlation is found between the regimes corresponding to percolation effects in the superconductor and to the transition from extended to confined superconductivity with the characteristic fields for reverse domain nucleation and fast domain expansion in the magnetic layer, indicating that superconductivity nucleates on the disordered network imprinted on the superconducting layer by the labyrinth domain structure of the magnetic layer. As disorder increases in the magnetic layer, percolation effects disappear from the superconducting transitions in agreement with a more homogeneous magnetization reversal process.

“…As a straightforward generalization, we will briefly discuss multi-domain cases at the end of Sec.III. Similar FM domain structures have been studied for general FM superconductors also in different contexts [24][25][26][27][28] . We consider an anisotropic system with an open boundary condition for x-direction and periodic boundary conditions for y, z-directions as shown in Fig.…”

Fulde-Ferrell state in a ferromagnetic chiral superconductor with magnetic domain walls

Motivated by the recent theoretical and experimental progress in the heavy fermion system UCoGe, we study ferromagnetic chiral superconductors in the presence of magnetic domains. Within mean field approximations, it is shown that chiral superconducting domains are naturally induced by the ferromagnetic domains. The domain wall current flows in the opposite direction to the naively expected one as in 3 He-A phase due to contributions from "unpaired electrons". Consequently, the domain wall current flows in the same direction with that of surface currents when the magnetic domain wall lies parallel to the sample surface, and therefore they contribute to the net current along the whole sample. We find that, due to the non-cancellation between the domain wall current and surface current, a Fulde-Ferrell-like superconducting state can be stabilized in an anisotropic sample for all the temperatures below the superconducting transition temperature.
