Electrical properties of M-type barium hexaferrites (BaFe12ZnMnO19)

Analysis Magnetic Mineral Content of Natural Iron Sand in Beach Island Lombok as Basic Materials of Micro Wave Absorbers

“…After that, a separation between magnetic minerals with sand has been paraded to get Fe3O4 (magnetite) powder. The results of the separation (Figures 2, 3, and 4) have high magnetic properties so that they are widely used as material for absorbing good microwaves (Doyan et al, 2020).…”

“…Lombok Island has a variety of sand colors caused by geological activity (Doyan et al, 2015). The difference in the sand is spread throughout the island, starting from the dark in the northern part of the island, to white in the southern part (Doyan et al, 2020). Coastal sand is often found in the coastal area of the island, but its processing is still rarely used in the field of infrastructure development because it has the characteristics of grains that are fine and rounded, have a large grain, and contain salt (Elinda et al, 2022).…”

Synthesis of Barium M-Hexaferrite Using Co-precipitation Method with Zn Doping Based on Natural Iron Sand at Tebing Beach, North Lombok as Microwave Absorbent Material

“…This shows that the higher the calcination temperature, the darker the color of the sample . This is because the solvent used has evaporated due to the calcination process (Doyan et al, 2020).…”

Coercivity, Activation Volumes, and Interactions in BaFe12O19

“…[ 21 ] However, the coercive field values usually reported for coprecipitated samples represent only 80% of the theoretical value of this model. [ 14,22–24 ] Then, despite these experimental values for H c , as a magnetization reversal mechanism in coprecipitated M hexaferrite samples, a nearly coherent rotation mechanism is assumed. In our work, we studied samples obtained by the coprecipitation method and also by the traditional ceramic method, to compare them.…”
