| Popis: | Bi 3+ -substituted Li 0.35 Zn 0.3 Bi x Fe 2.35-x O 4 (x = 0.1) nanocrystallites of ∼32 nm synthesized via a citrate-gel combustion and then annealed at 400 °C for 2 h in air shows a saturation magnetization M s = 11.25 emu/g (with a high coercivity H c = 273 Oe) at 5 K. Frequency ( f ) dependence of dielectric properties describes a mechanism of polarization. Granular crystallites offers a high polarization P s = 1.956 μC/cm 2 at 9 kV/cm applied field. |
