BaFe11.4Ce0.6O19/PPy

BaFe12-iCeiO19/polypyrene, i = 0.6; Data for composite BaFe12-iCeiO19/PPy with i = 0.6 was measured by a vector network analyzer (VNA) using E85071C with Keysight Technologies 85055AR03-FG Airline Type N, 50 Ohm Replacement Kit which was a standard setting for equipment used in microwave absorption material research. The thickness of the film was 2.15 mm. The film was prepared using the weight ratio of the composite to paraffin wax of 3:7 and was in a donut shape with inner and outer diameters of 3 and 7 mm, respectively.
