Using liquid helium, Kurti and co-workers and others, have succeeded in obtaining temperatures of a few microkelvins by the adiabatic demagnetization of copper nuclei. [Pg.7]

Figure 9 shows typical demagnetization curves for the materials of Table 8 (104,105). A material group may include more than one grade. In that case the values for the two extreme iC-values are given. [Pg.198]

In the case of Co—Cr having perpendicular anisotropy there is, in principle, a competition between the uniaxial anisotropy of a hexagonal stmcture and the demagnetizing energy of the thin film. In the case of magnetically separated Co—Cr columns (particulate morphology) then also the shape anisotropy contributes to the perpendicular anisotropy. [Pg.174]

Here iC is the intrinsic anisotropy constant due to the crystalline anisotropy. After the demagnetization in the longest direction, k is the shape-dependent constant (for an infinite cylinder k = 1.38), M is the exchange constant, and R the particle radius. An infinite cylinder with only shape anisotropy gives... [Pg.176]

In the transition from the demagnetized state (H = 0 Af = 0) to saturation (H = large M = ), small domains (aligned favorably with the field)... [Pg.177]

At low p.f.s the generator operates at a low level of excitations (armature reaction demagnetizing). During a fault, therefore, when the p.f. of the circuit falls it will also cause a fall in the excitation level and in turn in the terminal voltage. A low voltage, however, would reduce the severity of the fault. [Pg.503]
