Intrinsic hysteresis

For perm anen t-m agnet materials where the coercivity is large, the demagaetizatioa curve, which correspoads to the secoad quadrant of the hysteresis loop, sometimes is plotted as the polarization J(= B — vs H(B — H vs H) to show the intrinsic characteristics of the material. The value of... 

Thus this adhesion hysteresis is a result of a time-dependent roughening of the interface. It shows that roughness at an interface may actually develop as a result of bringing the two phases together as a result of the intrinsic properties of the surface molecules. 

A limited amount of trapping (either intrinsically or extrinsically) is helpful in that it ensures a deep OFF state of the device during the time at which other lines are addressed that is a (properly adjusted) hysteresis can serve as a memory element over the frame time (Ast, 1982a,b, 1983). This argument is not readily accepted by those who believe that a device must be inherently stable to function in a reliable manner. However, Luo et al. (1983) arrived at an identical conclusion in their analysis of the switching performance of CdSe transistors in matrix-addressed LC displays. It is very important that the trapping be noncumulative. Since the duty cycle of a... 

Intrinsic defects in molecular solids. Figure 4.14 shows the variations of r3 with T in succinonitrile [125, 129]. As sulfolan, this compound exhibits a brittle (monoclinic) phase up to 233 K, then a plastic body-centered cubic phase. The phase transition is well evidenced, with some hysteresis. However, above the phase transition point, x3 increases further in a sigmoidal way characteristic of defect formation. By using Eq. (24), the activation energy of the intrinsic molecular defect is obtained (0.36 eV). Analyzing the PALS spectra in four components confirms that x3 does represent the average between an o-Ps bulk lifetime, which decreases with T, and the constant lifetime of o-Ps trapped in the vacancies whose intensity increases with T. 

Intrinsic hysteresis is a direct result of surface configuration change, which occurs as a result of wetting the surface with water. The plates were purposely immersed to a deeper immersion depth in the second cycle to observe the extent of intrinsic hysteresis. Significant surface configuration change affects the calculated contact angles on immersion and emersion, which violates the assumption of... 

Figure 26.17 Effect of plasma treatment on the intrinsic hysteresis, which is the difference in second cycle immersion line and the first cycle immersion line, (AC/L) = (C/Llu 2 — Fj T)D,a,i intrinsic hysteresis is directly proportional to the extent of surface configuration change of the surface state.

In general, dynamic hysteresis is smaller with smaller cross-sectional area because the effect of buoyancy is less. Thus, the dynamic hysteresis is not a measure of surface characteristics. Intrinsic hysteresis is a measure of the surface dynamic stability of the surface. 

Wilhelmy plate wetting parameters, such as plate velocity during immersion or emersion and halting the motion of the plate after immersion or emersion, have been shown to alfect the intrinsic hysteresis, which consequently affects the overall shape of the force loop [3]. These wetting parameters were found to affect FHT differently depending on whether pure water or an aqueous artificial tear solution was employed as the wetting medium.
