LANTHANUM (La^3+) SUBSTITUTION FOR Fe^3+ IN Ba–Sr-Ca M-TYPE HEXAFERRITES AND THEIR SYNTHESIS AND CHARACTERIZATION [PDF]
European Journal of Materials Science and Engineering, 2020 We have synthesized three different hexagonal Magnetoplumbite (M) types of ferrites by standard ceramic method at a high temperature of 1403 K. These ferrites are namely Lanthanum La substituted for Fe in Barium (BaLa0.2Fe11.8O19), Strontium (SrLaFe11O19)

Coupling between improper ferroelectricity and ferrimagnetism in the hexagonal ferrite LuFeO_{3}
Physical Review Research, 2023 Here, we propose an idea to realize noncollinear ferrimagnetic orders with a considerably high magnetization M and their coupling with an improper ferroelectric (FE) order in hexagonal LuFeO_{3} type systems which exhibit interesting topological orders ...
