TEM images of partially ordered FePt nanoparticles in different solvents: (a) hexane and (b) cyclohexanone with PVC coating.
(a) In-plane hysteresis loop and remanence curve for partially ordered FePt nanoparticles. (b) In-plane hysteresis loops for applied field parallel (solid line) and perpendicular (dashed line) to the aligning direction. All measurements are done at room temperature.
The angular dependence of (a) coercivity and (b) squareness for partially ordered FePt particles aligned under a field. The lines are drawn as a guide for the eye.
XRD patterns for FePt nanoparticles: (a) before and (b) after aligning.
