Microwave property of micron and sub-micron Fe90Al10 flakes fabricated via ball milling and jet milling routes

► We firstly use jet mill to produce alloy flakes in nanoscale. ► We prepare Fe/Al flakes in micron and nanoscale by combining the ball milling (dry mill and wet mill) and jet milling. ► Based on Fe/Al flakes with different sizes, their microwave performance was studied. ► The as-prepared 500 nm-flakes were found to be good for high frequency application.
