Manufacturing, Characterization, and Simulation Model Design for a Current Sensor Based on a Spin-Valve Magnetoresistive Microstructure

Elena M. Stetco et al.

Summary: This paper describes and validates two PSpice models for a current sensor based on spin-valve magnetoresistive microstructures. The magnetic spin-valves are patterned, optimized, and characterized in terms of magnetoresistive ratio, sensitivity, and linearity. One model is implemented using the lookup table method, while the other model is based on the analytical description of the experimental characteristics and the implementation of a higher order polynomial. Experimental data is interpolated in MATLAB and used as input data for the PSpice models. Once validated, these PSpice models can be used to model the behavior of other types of magnetoresistive structures and easily adapted to integrated sensors produced by industrial manufacturers.

Highly-sensitive magnetic sensor for detecting magnetic nanoparticles based on magnetic tunnel junctions at a low static field

Z. Jin et al.

Summary: The magnetic sensor with MTJ structure and synthetic antiferromagnetic free layer demonstrates high sensitivity at low magnetic fields. It can detect superparamagnetic MNPs with a diameter of 200 nm and shows high sensitivity to changes in MNP concentrations, capable of detecting MNP amounts below 500 ng and concentrations of 0.01, 0.1, 1 mg/ml in solvents. The combination of high-sensitivity TMR sensors and large MNPs has significant potential for biomarker detection applications.
