Paramagnetic singularities of the orbital magnetism in graphene with a moiré potential
J. Vallejo Bustamante, R. Ribeiro-Palau, C. Fermon +9
The recent detection of the singular diamagnetism of Dirac electrons in a single graphene layer paved a new way of probing 2D quantum materials through the measurement of equilibri…
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…
Detection of graphene's divergent orbital diamagnetism at the Dirac point
J. Vallejo, N. J. Wu, C. Fermon +12
The electronic properties of graphene have been intensively investigated over the last decade, and signatures of the remarkable features of its linear Dirac spectrum have been disp…
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…
