Figures & data

Figure 1. (A) Schematic of a hysteresis loop showing the important parameters. (B) Hysteresis loops as a function of frequency on a magnetic nanoparticle system. (Reprinted with permission from Eggeman et al. [48].).

Figure 2. (A) SLP generated by four different magnetic nanoparticle systems dispersed in water as a function of maximum magnetic field at a fixed frequency of 150 kHz. Highlighted area in (A) is shown in (B) as a close-up of the SLP in low field amplitudes. (Figure courtesy of Anilchandra Attaluri.).

Figure 3. Minor loops for randomly oriented nanoparticles with fixed magnetic field amplitude (10 Oe) and fixed frequency as a function of magnetic anisotropy energy density in ergs/cm³, where K = (A) 1 × 10⁵, (B) 2 × 10⁵, (C) 3 × 10⁵, (D) 4 × 10⁵, (E) 5 × 10⁵, (F) 6 × 10⁵, (G) 7 × 10⁵, (H) 8 × 10⁵, and (I) 9 × 10⁵.

Figure 4. Heat (W, in dimensionless units) produced during one cycle as a function of field amplitude (p0, in dimensionless units where p = mH/U) in 1) liquid, and 2) solid dispersion. (Reprinted with permission from Kashevsky et al. [77].).
