Constant TMR magnetic field sensor detectivity with bias voltage
E. Monteblanco, A. Solignac, C. Chopin +6
In this letter, we present a study of optimized TMR magnetic field sensors as a function of voltage bias. The 1/f low-frequency noise is quantified by the Hooge-like parameter α wh…
Spin-torque Dynamics for Noise Reduction in Vortex-based Sensors
Mafalda Jotta Garcia, Julien Moulin, Steffen Wittrock +12
Performance of magnetoresistive sensors is today mainly limited by their 1/f low-frequency noise. Here, we study this noise component in vortex-based TMR sensors. We compare the no…
Normalization and electronic circuit correction for magnetic tunnel junction sensor performances comparison
E. Monteblanco, A. Solignac, C. Chopin +6
In this manuscript we propose a theoretical model where the magneto-resistive elements are modelled as fluctuating resistances to correct the output voltage noise of tunnel magneti…
Multi-GMR sensors controlled by additive dipolar coupling
J. Torrejon, A. Solignac, C. Chopin +5
Vertical packaging of multiple Giant Magnetoresistance (multi-GMR) stacks is a very interesting noise reduction strategy for local magnetic sensor measurements, which has not been…
Optimizing magnetoresistive sensor signal-to-noise via pinning field tuning
J. Moulin, A. Doll, E. Paul +4
The presence of magnetic noise in magnetoresistive-based magnetic sensors degrades their detection limit at low frequencies. In this paper, different ways of stabilizing the magnet…
