Hi, thanks for your interest. At this moment we are working on two papers related to this topic. One of them will be more extensive and somehow summarize our main results. For now, we have published some papers on anisotropic nanostructures. See for example:
+ R. Das et al. “Tunable High Aspect Ratio Iron Oxide Nanorods for Enhanced Hyperthermia”. J. Phys. Chem. C - 120, 10086–10093 (2016)
+ Z. Nemati et al. “Enhanced Magnetic Hyperthermia in Iron Oxide Nano-Octopods: size and anisotropy effects” J. Phys. Chem. C - 120, 8370–8379 (2016)
+ H. Khurshid et al. “Anisotropy effects in magnetic hyperthermia: A comparison between spherical and cubic exchange-coupled FeO/Fe3O4 nanoparticles” J. Appl. Phys. 117, 17A337 (2015)
+ J. Alonso et al. “FeCo nanowires with enhanced heating powers and controllable dimensions for magnetic hyperthermia” Journal of Applied Physics 117, 17D113 (2015)
