Figure 4From: Nearly Monodispersion CoSm Alloy Nanoparticles Formed by an In-situ Rapid Cooling and Passivating Microfluidic ProcessThe amorphous CoSm nanoparticles show a wasp-waist hysteresis loop at 10 K with an average coercivity of 225 Oe (right-bottom inserted image) and a Hc of 5 Oe at 300 K (a); the FC and ZFC magnetization curve of CoSm nanoparticles suggest a blocking temperature at 40 K (b)Back to article page
