Nonmonotonic critical temperature in superconductorÕferromagnet bilayers
The critical temperature Tc of a superconductor/ferromagnet ~SF! bilayer can exhibit nonmonotonic dependence on the thickness d f of the F layer. SF systems have been studied for a long time; according to the experimental situation, a ‘‘dirty’’ limit is often considered which implies that the mean free path in the layers is the second smallest spatial scale after the Fermi wavelength. However, ...
متن کاملJianxin Tang Nonmonotonic Temperature Seth
We present two experiments that probe the temperature dependence ofthe flexibility ofthe filamentous virus fd by examining aspects ofthe liquid crystalline nature qf fd suspensions. The first measurement i s of the temperature variation o f the coexisting fd concentrations at the isotropic-cholesteric phase transition. The second measurement is ofthe magneticfield induced birefringence or Cotto...
متن کاملCritical Swelling of Phospholipid Bilayers
We reexamine a critical phenomenon of phospholipids in lamellar phases. The question is, Is the anomalous divergence in the repeat spacing near the main transition the result of a divergence of the water layer or of the lipid bilayer? X-ray diffraction of DLPC lamellae was measured in partially dehydrated conditions. Its critical behavior is much more pronounced than the previously studied DMPC...
متن کاملCritical supercurrents and self-organization in quantum Hall bilayers.
We present a theory of interlayer tunneling in a disordered quantum Hall bilayer at total filling factor one, allowing for the effect of static vortices. In agreement with recent experiments [Phys. Rev. B 80, 165120 (2009); Phys. Rev. B 78, 075302 (2008)], we find that the critical current is proportional to the sample area and is comparable in magnitude to observed values. This reflects the fo...
متن کاملFinite-temperature pseudospin torque effect in graphene bilayers
We use self-consistent quantum transport theory to investigate the influence of layer Fermi energy and temperature on the interlayer transport properties of bilayer graphene in the regime of excitonic superfluidity. We conclude that at low temperature the critical tunneling currents and quasiparticle penetration depths are well explained by the existing zero-temperature pseudospin torque model....
