Barium hexaferrite ceramic permanent magnets
Suid-Afrikaanse Tydskrif vir Natuurwetenskap en Tegnologie, 1983 Barium hexaferrite ceramic permanent magnets were manufactured using a locally produced iron oxide. The effect of sintering temperature on the coercivity, remanence, shape of the hysteresis loops, density and shrinkage was studied. The results indicated that grain growth during the sintering process limited the sintering temperature to 1 200 °C for ...

Photoluminescence behaviour of Gd doped barium hexaferrite
IOP Conference Series: Materials Science and Engineering, 2020 Abstract This paper reports synthesis of Barium Hexaferrite with different concentration of Gadolinium ion (0-2 mol %). Structural analysis of the prepared powders was done by X-ray diffraction pattern which reveals formation of hexagonal structure with space group p63/mmc.
