IIR documentSummary
A numerical model is used to study demagnetizing effects in a single-material AMR. The use of additional passive magnetic material to reduce demagnetization is examined and suggests that augmenting the effective field, H, is possible. Numerical results are validated with experiments near room temperature using AMRs consisting of Gd and Gd(0.74)Tb(0.26) adjacent to layers composed of passive magnetic material. Experimental data show an increase in the no-load temperature span for certain operating conditions and confirm the beneficial impact of using passive magnetic material to reduce demagnetization effects.
