Samples of YBa2 Cu3Ox doped with silver oxide (Tc ∼93 K) have exhibited attractive forces in gradient magnetic fields, both normal and tangential to the surfaces, which are more than twice the sample weight. This allows sample suspension below a rare earth magnet. Critical current density was increased by ∼102 at 77 K. Persistent fields, flux pinning, magnetization, and modeling are described.

In addition to the usual inverse distance singularity, two singular terms are generally present. The first of...

    We have measured the effect of a magnetic field on the surface resistance of polycrystalline Cu at f=1.2 GHz and at 4.4 K; under these conditions the surface resistance is well into the anomalous skin effect regime but has not reached its limiting value. We find that the transverse and...

The model discussed here consists of an extended antiferromagnetic surface step at the surface boundary of an insulating antiferromagnetic substrate.

    Jets and outflows are observed around a wide variety of accreting objects and seem to be a near-ubiquitous feature of accretion disks. Large-scale magnetic fields are thought to be necessary for jet formation in many systems, but a longstanding puzzle is that the turbulence which is responsible...
