In this paper, we present the giant-magneto-impedance (GMI) effect in a microfabricated closed Permalloy core which surrounds a copper excitation rod. We measured a 90% change in the inductance value of the device for a sinusoidal excitation at 500 kHz in ...
We study the magnetic susceptibility of the novel metal-organic framework [Cu3(mu3O)(mu3trz)3(OH)(H2O)6. The magnetic susceptibility is measured using a SQUID magnetometer. Exact diagonnalization and mean Field theory are then used in an attempt to Fit the ...
We developed a new integrated magnetic sensor based on the Hall effect, suitable for the application in magnetic contactless 360° absolute angle sensors. The device consists of a narrow n-well ring with a chain of 64 contacts equally distributed around the ...

A semi-empirical potential for ferromagnetic bcc iron that also models the co-linear magnetic moment of each atom, has been applied to clusters and surfaces. Surface energies of low index facets, surface relaxation and magnetic moment are calculated and co ...

For most of the last forty years, the techniques of Dynamic Nuclear Polarization (DNP) have been confined to particle-physics laboratories building polarized targets, but recently it has been shown that samples similar to a solid target can be transformed ...
This paper presents a new technique for continuously calibrating the sensitivity of a current measurement microsystem based on a Hall magnetic field sensor. An integrated reference coil generates a magnetic field for calibration. Using a variant of the cho ...
The first commercially available teslameter with a fully integrated three-axis Hall probe is described. The Hall probe chip contains horizontal and vertical Hall elements, analog electronics, and a synchronization circuit. A horizontal Hall element measure ...
