The magnetoquenched superconducting valve is a nonvolatile switch consisting of a ferromagnetic film that spans a superconducting strip. A device state is dictated by the magnetization orientation of the ferromagnetic element and the corresponding ma

In a simple bilayer geometry, a thin, microstructured ferromagnetic film spans a superconducting strip. Locally strong magnetic fringe fields at the edge of the ferromagnet quench the superconductivity, creating a weak link. The strength of the weak

In this paper, we study the magnetization reversal process of single-domain Stoner-Wohlfarth particles subject to circularly polarized fields and short pulses using analytical and numerical models. We investigate the effect of short unipolar, bipolar

High-frequency characterization of perpendicular media is demonstrated on disk with a novel nondestructive local probe. The probe is micron-scale and has high bandwidth. We measure the permeability of the soft underlayer (SUL) and observe its ferroma

Using the micromagnetics package MAGPAR, we study the ground states of NiFe nanorings with sub-100-nm lateral dimensions, in zero external field. We solve the Landau-Lifschitz-Gilbert equation for three different initial magnetizations (in plane, out

We have investigated the pinning and magnetic-field dependence of the mixed-state Hall conductivity ${\ensuremath{\sigma}}_{\mathrm{xy}}$ in thin films of two superconductors, amorphous ${\mathrm{Mo}}_{3}\mathrm{Si}$ and ${\mathrm{YBa}}_{2}{\mathrm{C

We measured the longitudinal and Hall resistive transitions of ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}}}$ films in applied fields up to 9 T. The longitudinal fluctuation conductivities

At 1 Tbit/in 2 areal density magnetic recording dimensions, reliable magnetic field metrology does not exist. One technique to map the spatial profile of the magnetic field of a write head is to use a contact read/write tester. A magnetic recording h

We have studied the role of pinning in the mixed-state thermomagnetic transport properties of $\mathrm{Y}{\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$. We demonstrate the pinning independence of the transport en

A focused ion beam (FIB) is used to fabricate single-pole perpendicular writers by micro-machining longitudinal (ring) heads at the HGA. The heads are designed for media characterization, and a comparison is made between the performance of the FIBed
