Skyrmion-(Anti)Vortex Coupling in a Chiral Magnet-Superconductor Heterostructure.

We report experimental coupling of chiral magnetism and superconductivity in [IrFeCoPt]/Nb heterostructures. The stray field of skyrmions with radius ≈50 nm is sufficient to nucleate antivortices in a 25 nm Nb film, with unique signatures in the magnetization, critical current, and flux dynamics, corroborated via simulations. We also detect a thermally tunable Rashba-Edelstein exchange coupling in the isolated skyrmion phase. This realization of a strongly interacting skyrmion-(anti)vortex system opens a path toward controllable topological hybrid materials, unattainable to date.

This study presents the experience of an obstetric nurse and of a couple who had their third child. It focuses on care standards that value women and couples in the childbirth and delivery process. It describes the care given to a couple during the pregnancy stage and during home delivery. The experience enabled the active participation of the couple and their children in the childbirth process, which essentially provided satisfaction to the family and to the professional.
