“…The spin-valves studied have the magnetic layer configuration 3.5 nm Ta/8.0 nm F/t Cu /6.0 nm F/10.0 nm Fe 50 Mn 50 / 3.5 nm Ta which is shown schematically in figure 1. F is a ferromagnetic alloy, either permalloy (Py), or Ni 66 Fe 16 Co 18 , the latter composition chosen because it lies close to the zero magnetostriction line on the NiFeCo ternary phase diagram [20][21][22]. The thickness of copper is given by t Cu which in the range 2-10 nm.…”

Transmission electron microscopy has been used to investigate the 'free' layer reversal mechanism of a range of FeMn-biased spin-valves with parallel anisotropy. Fresnel imaging enabled three modes of reversal to be directly observed for different in-plane applied field orientations and interlayer coupling strengths. Low-angle diffraction has provided some quantitative information on the level of dispersion involved in the reversals. Comparison with a modified Stoner-Wohlfarth coherent rotation model is made and magnetic modelling of the free layer energy variation as a function of magnetization orientation is presented. This has helped provide a deeper understanding of the observed discrepancies between the model and experimental data. Finally, a qualitative description of the observed domain processes is given in relation to the free layer energy for the corresponding experimental conditions.

“…Recently, another effect has attracted the interest of the field sensor market and more importantly, the recording media market. This is the spin valve effect [86][87][88][89][90], according to which a specially designed magnetic arrangement exhibits non-symmetrical B-H response. This property allows very well localized field measurements with an acceptable accuracy.…”

A review of the engineering theory and the sensing element applications of the magnetostrictive delay line (MDL) technique is presented. The state of the art of magnetic materials and effects used in sensor design is overviewed and the operation of MDLs and their basic engineering properties are discussed. The resulting position, stress and field sensors based on this technique as well as their most significant applications are demonstrated. Finally, the industrialization process and the integration of the sensors with electronic circuitry as well as their evaluation with respect to the state of the art are discussed.
