Simple linearising front‐end‐circuit for giant magneto‐resistance sensors

Microfluidic Biosensing using Giant Magnetoresistance Sensors

Giant Magnetoresistance

In today’s world of portable, high capacity music players and consumer hard drives with storage sizes of up to a terabyte, the ubiquitousness of information and the space to store it seems to be almost taken for granted in our society. However, the emergence of such vast and economical storage of data has only occurred within the past 10 years. The most prominent driving force of this technolog...

Giant Magnetoresistance

The discovery of giant magnetoresistance (GMR) has been a huge impact on our life, especially for mass data storage devices. Initial experiments conducted by Gruberg and Fert are explained. Basic physics of the GMR effect can be explained by the two-current model, which the conduction of a current is consist of two different spin electrons. Details of GMR applications, such as hard-disk read-he...

Anisotropic- Magnetoresistance Integrated Sensors

In this paper. a short overview is presented of the most widely used types of solid state magnetic sensor. These sensors are applied in many areas, such as the measurement of magnetic fields and in compasses, angle/position sensors and current sensing. Hall effect, AMR (Anisotropic Magnetorestance-effect) and GMR (Giant Magnetoresistance-effect) sensors are the most frequently used. In spite of...
