Magneto electronics applications
FREE-DOWNLOAD [PDF] GA Prinz – Journal of magnetism and magnetic materials, conducting layers separated by a very thin insulating layer which acts as a barrier to electrical conduction. with essentially a four-point probe arrangement attached to every device, two of which provide current and the other two permit an independent voltage measurement.
AMR sensor-based measurement
An AMR sensor-based measurement system for magnetoelectrical resistivity tomography FREE-DOWNLOAD [PDF] E Zimmermann, A Verweerd, W Glaas… – Sensors Journal, … Each measurement consists of two samples, a homogeneous one and a disturbed one. Then, by calculating the difference of both data sets, the effect of current flowing through electric wires and in the circuits is nullified, leaving only the effect […]
