摘要: The interesting magnetic response of conventional ferro-colloid has proved extremely useful in a wide range technical applications. Furthermore, the use nano/micro- sized particles proliferated cutting-edge medical research, such as drug targeting and hyperthermia. In order to diversify improve application systems, new avenues functionality must be explored. Current efforts focus on incorporating directional interactions that are surplus intrinsic one. This additional directionality can conveniently introduced by considering systems composed different shapes. Here we present combined analytical simulation study permanently magnetized dipolar superball particles; geometry closely resembles cubes synthesized experiments. We have focused determining initial susceptibility these dilute suspensions, seeking quantify effect shape parameter s...
