Thin magnetic anisotropy

Since thin magnetic films are deposited on a non-magnetic substrate, the actual strains, and thus the induced anisotropy, depend on the magnetoelastic coupling coefficients of... [Pg.103]

Figure 4.34. Time-independent part of the orientation parameter as a function of the field frequency for different values of the internal magnetic anisotropy of the particles. The ratio e = TdAb = 1CT4 curves correspond to a = 100 (1), a = 10 (2), o = 5 (3), a = 2 (4), a = 0.1 (5). Thin lines a and b resemble the limiting behavior predicted by the rigid and soft dipole models, respectively. Note that at this graph the lines a and 1 visually coincide. Figure 4.34.

Figure 4.35. The second-harmonic amplitude of the orientation parameter for different values of the internal magnetic anisotropy of the particles. The set of material parameters and meanings of the thin curves are the same as those for Figure 4.34. Figure 4.35. The second-harmonic amplitude of the orientation parameter for different values of the internal magnetic anisotropy of the particles. The set of material parameters and meanings of the thin curves are the same as those for Figure 4.34.
The EMR spectra of polymer films prepared without external field demonstrate quite broad lines (Figure 3). Center of these lines is strongly dependent on the sample orientation in MF of spectrometer. This results from the anisotropy of demagnetizing fields, which determine resonance conditions for the thin magnetic film ... [Pg.52]

Fig. 7.9 M-H hysteresis loops of SmCOj thin films with perpendicular magnetic anisotropy, (a) Sample A, (b) sample B, and (c) sample C correspond to those in Table 7.1. Thick and thin lines represent the loops measured in the directions perpendicular and parallel to the film plane, respectively [45]...
