WebThe value of the magnetostriction constant λ s is determined on the falling parts of the measured AMR curves in the region of longitudinal magnetic H > H a . A certain fixed value of the EMF of the second harmonic U 2f 1 is selected, for which the H–σ app diagram is constructed and the ratio ∆ H/ ∆ σ app is determined. WebThe curves of magnetostriction as shown in Figure 3a show that all MRE samples are experiencing an increase in magnetostriction under the influence of a magnetic field, indicative of the fact that the samples were elongated. The general behavior of such an increase in magnetostriction can be divided into three main stages.
