The detection of single molecules, e.g. in biology is possible by marking the interesting molecules with magnetic beads and detect the influence of the beads on giant magnetoresistance (GMR)/tunnel magnetoresistance (TMR)/spin valve (SV) sensors. The

Tunnel magnetoresistance curves were measured in very small tunnel junctions from scales of I Am to 50 nm using conductive atomic force microscopy. The junction arrays were prepared by a simple fabrication process using electron beam lithography. In

Fast MR imaging methods should provide a familiar contrast behavior at a reduced scan time. The multi-spin echo approach (TSE) is one of the most promising techniques satisfying this condition. Although the data acquisition time is significantly redu

The signal response of Bangs Laboratories magnetic markers with a mean diameter of 0.86 /spl mu/m on a spiral-shaped giant magnetoresistance sensor with a diameter of 70 /spl mu/m is investigated. The data show a linear dependence of the sensor signa

Conducting atomic force microscopy was used for the characterization of magnetic tunnel junctions with various areas down to a minimum of 0.0025 mum(2) and a tunnel magnetoresistance (TMR) value up to 20%. Minor loops of large junctions show jumps, o

The high effect amplitude of {Cu/Py} multilayers at first antiferromagnetic coupling maximum (AFCM) can be combined with the temperature stability of multilayers at second AFCM by using both corresponding copper layer thicknesses in one multilayer st

The results of micromagnetic calculations of GMR sensors are shown under the influence of the stray fields of magnetic beads (microspheres), aligned out of plane or in plane of the sensor layers. These detection cases show very different characterist

A new scheme of combined movement by on-chip currents and detection of magnetically labeled biomolecules has been introduced. This was the first step on the way to an on-chip laboratory. A conductor pair has been placed to this end on both sides of t
