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 ...

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 ...
A CMOS HALL magnetometer is presented herein that can be optimally used in current sensing applications thanks to its specific features. The magnetometer incorporates a set of integrated coils that generate a reference AC magnetic field to allow for sensit ...

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 ...
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 ...
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 ...
