Permanent magnets have attracted research interest in the last decades as they are used in a wide range of applications, in consumer electronics, motors, electric generators, and nano-micro scale applications [microelectromechanical systems (MEMS) and nanoelectromechanical systems (NEMS)]. Plastic-bonded magnets (PBMs)—composites with permanent magnetic powder embedded in a polymer binder—are considered...
MnBi has recently attracted large attention due to its potential for permanent magnetic applications. Although it does not present high saturation magnetization, it has large coercivity, above 1 T, which results in a theoretical BHmax value above 17 MGOe [1-2]. The MnBi single phase is difficult to prepare by using techniques as arc-melting, rapid solidification and sintering because the melting temperature...
