• . Another idea is to use elongated magnetic nanoparticles [9][31][32][33][34][35][36], which in a number of experiments [31][33] showed a rather high SAR. It is well known that elongated magnetic nanoparticles can be easily oriented in external magnetic fields. Furthermore, oriented assemblies of

• nanoparticles showed increased SAR [37][38] when the ac magnetic field was applied parallel to the assembly orientation axis. It is worth mentioning that, in nature, some strains of magnetotactic bacteria can synthesize elongated magnetic nanoparticles [39][40][41]. Biogenic magnetic nanoparticles have a
