Family life starts at home: Fathers' experiences of a newly implemented Swedish home-based postnatal care model - an interview study.

OBJECTIVE: To explore and describe fathers' experiences of a newly implemented Swedish home-based postnatal care model. DESIGN: A descriptive cross-sectional qualitative study was conducted as a part of a larger study. SETTING: Families who qualified to be discharged early were offered to participate in a postnatal home-based model of midwifery care by a hospital in Stockholm, Sweden. PARTICIPANTS AND MEASUREMENTS: In total, 16 fathers participated in a semi-structured telephone interview, averaging 43 min. Data were analyzed using systematic text condensation. FINDINGS: Three major themes emerged: To decide on home- or hospital-based postnatal care - a matter of safety, To be offered professional midwifery postnatal support at home, and To be at home helped fathers to navigate parenthood. Fathers appreciated the home-based postnatal care and felt safe because of the received professional support from midwives. KEY CONCLUSIONS: Home-based postnatal care was valued by fathers whose partner had a non-complicated vaginal birth because they felt safe in their home environment and supported by midwives. The home environment aided fathers in supporting their partners and developing a father-infant bond. IMPLICATIONS FOR PRACTICE: Home-based postnatal care was valued by fathers and should be considered an option for new families. To offer home-based postnatal care may result in less overcrowded postnatal wards. Midwives need to enable fathers' participation and support their parental role regardless of where the care takes place.

Spin Superfluidity in Biaxial Antiferromagnetic Insulators.

Antiferromagnets may exhibit spin superfluidity since the dipole interaction is weak. We seek to establish that this phenomenon occurs in insulators such as NiO, which is a good spin conductor according to previous studies. We investigate nonlocal spin transport in a planar antiferromagnetic insulator with a weak uniaxial anisotropy. The anisotropy hinders spin superfluidity by creating a substantial threshold that the current must overcome. Nevertheless, we show that applying a high magnetic field removes this obstacle near the spin-flop transition of the antiferromagnet. Importantly, the spin superfluidity can then persist across many micrometers, even in dirty samples.

Spin Superfluidity and Long-Range Transport in Thin-Film Ferromagnets.

In ferromagnets, magnons may condense into a single quantum state. Analogous to superconductors, this quantum state may support transport without dissipation. Recent works suggest that longitudinal spin transport through a thin-film ferromagnet is an example of spin superfluidity. Although intriguing, this tantalizing picture ignores long-range dipole interactions; here, we demonstrate that such interactions dramatically affect spin transport. In single-film ferromagnets, "spin superfluidity" only exists at length scales (a few hundred nanometers in yttrium iron garnet) somewhat larger than the exchange length. Over longer distances, dipolar interactions destroy spin superfluidity. Nevertheless, we predict the reemergence of spin superfluidity in trilayer ferromagnet-normal metal-ferromagnet films that are ∼1 µm in size. Such systems also exhibit other types of long-range spin transport in samples that are several micrometers in size.
