Figure 12: Calculated magnetic loss for core-shell nanoparticles in AC magnetic fields for various and . Rotatable nanoparticles are compared with randomly oriented ones. The dashed lines show the isoplethic curves at and 1 MW/kg, while the solid lines show the isoplethic curves at the selection ratio (see Figure 11). *Reproduced from Mamiya [72] with permission (Copyright 2012 TIC).
