Ferrofluid nucleus phase transitions in an external uniform magnetic field |
Resulted thermodynamically equilibrium structures: perspective projections (area with largest particles is highlighted); L = 0.3 μm. A size of volumetric arrows is proportional to a geometrical size of the corresponding nanoparticle for an illustrative purpose only. (a) H 0 = 0 Oe and T = 50 °C, (b) H 0 = 0 Oe and T = 75 °C, (c) H 0 = 200 Oe and T = 35 °C, (d) H 0 = 200 Oe and T = 55 °C, |
