|Abstract:||The spark eroded (SE) monophasic icosahedral powder has been synthesised in a nominal composition Al50Mn20Si30 and characterised by magnetic susceptibility and EPR measurements. Magnetic susceptibility exhibits a combination of Curie like behaviour and Pauli paramagnetism between 10 and 300 K. The EPR spectra exhibits two resonances at g almost-equal-to 2.07 and 3.91 at liquid nitrogen temperature while the room temperature spectra has only the former resonance. The results have been compared with that of a similar alloy synthesised by melt spinning. The differences have been attributed due to inherent increased disorder in SE sample owing to the different method of preparation.|
