We study a ferromagnetic chiral superconductor in the presence of magnetic domains with a focus on the heavy fermion system UCoGe. 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…

Enhancement of superconductivity by pressure-induced critical ferromagnetic fluctuations in UCoGe

A $^{59}$Co nuclear quadrupole resonance (NQR) was performed on a single-crystalline ferromagnetic (FM) superconductor UCoGe under pressure. The FM phase vanished at a critical pressure $P_c$, and

Nonthermodynamic nature of the orbital angular momentum in neutral fermionic superfluids

We discuss the orbital angular momentum (OAM) and the edge mass current in neutral fermionic superfluids with broken time reversal symmetry. Recent mean field studies imply that total OAM of a



Domain-wall superconductivity in hybrid superconductor-ferromagnet structures

On the basis of a phenomenological Ginzburg-Landau approach we investigate the problem of order parameter nucleation in hybrid superconductor-ferromagnet systems with a domain structure in an applied

Spontaneous Supercurrents in a Chiral p-Wave Superconductor

The superconducting state of SRO is widely believed to have chiral p-wave order that breaks time reversal symmetry. Such a state is expected to have a spontaneous magnetization, both at sample edges

Magnetism and superconductivity in ferromagnetic heavy-fermion system UCoGe under in-plane magnetic fields

We study the ferromagnetic superconductor UCoGe at ambient pressure under ab-plane magnetic fields H, which are perpendicular to the ferromagnetic easy axis. It is shown that, by taking into account

Topological properties of ferromagnetic superconductors

Here, a variety of heavy fermion superconductors, such as UCoGe, UGe2, and URhGe exhibit a striking coexistence of bulk ferromagnetism and superconductivity. In the first two materials, the magnetic

Domain wall superconductivity in ferromagnetic superconductors

On the basis of a phenomenological Ginzburg-Landau approach we investigate the problem of triplet order parameter nucleation in a ferromagnetic superconductor with a domain structure in an applied

Superconductivity on the border of weak itinerant ferromagnetism in UCoGe.

The proximity to a ferromagnetic instability, the defect sensitivity of T(s), and the absence of Pauli limiting, suggest triplet superconductivity mediated by criticalferromagnetic fluctuations.

Superconductivity in a Strong Spin-Exchange Field

A strong exchange field, such as produced by ferromagnetically aligned impurities in a metal, will tend to polarize the conduction electron spins. If the metal is a superconductor, this will happen

Superconductivity on the border of itinerant-electron ferromagnetism in UGe2

The observation of superconductivity on the border of ferromagnetism in a pure system, UGe 2, which is known to be qualitatively similar to the classic d-electron ferromagnets, is reported.

Spin-Triplet Superconductivity Induced by Longitudinal Ferromagnetic Fluctuations in UCoGe: Theoretical Aspect

Identification of pairing mechanisms leading to the unconventional superconductivity realized in copper-oxide, heavy-fermions, and organic compounds is one of the most challenging issues in

Domain structure in a superconducting ferromagnet.

It is demonstrated that superconductivity leads to a dramatic shrinkage of the domain width, applicable to both singlet and triplet superconductors.
