Magnetic CrX and MnX (XÂ =Â Si, Ge, and As) nanowires: Stability enhancement and linearization

► A very high value of cohesive energy for binary nanowires has been obtained. ► Magnetic moment per formula unit for binary nanowires is large. ► In binary MX nanowires, cohesive properties are steered by the X atoms. ► Magnetic properties of binary nanowires are governed by the metal atoms.
