On the microwave absorption of magnetic nanofluids based on barium hexaferrite in the S and X bands prepared by pulsed laser ablation in liquid

Magnetic nanofluids can be prepared by dispersing surfacted nanoparticles in an appropriate carrier medium. The microwave absorbing properties of a magnetic nanofluid based on barium hexaferrite (BAF) is promising since BAF is a good microwave absorber. Surfacted BAF particles prepared by Pulsed Laser Ablation in Liquid (PLAL) overcome agglomeration and are stable under normal conditions. The evaluation of parameters namely ε′, ε″, μ′ and μ″...
