D3.2 - EMR Component Report

This document, D3.2 – EMR Component Report, defines the design, fabrication, characterization and testing of the magnetoresistive (MR) component.

The document discusses:

-       The choice of material for the MR component in the context of NOVETROL project

-       The differences between developing a MR device for sensing applications based on the effect commonly labelled as extraordinary magnetoresistance (EMR) and developing a MR device for current limiting applications

-       The development of analytical expressions to estimate the resistance of the MR element with and without the presence of a magnetic field as a function of geometry and relevant material properties

-       The modelling and simulation of such devices via Finite Element Modelling (FEM) approach using commercial software

-       The fabrication procedure followed in clean room environment to obtain the desired components as designed

-       The characterization steps used in the Magnetics Laboratory to obtain experimental data from the samples, and understand their electrical and magnetic behaviour

From requirements defined previously in D2.1 - Report on NOVETROL Use Cases and Scenarios and D3.1 - System Specifications, a set of resistance values at zero and high magnetic fields for each use case can be obtained, which will guide the design of the MR elements.
