Influence of sintering atmosphere on the magnetic after-effect in strontium ferrites

Synthesis, physical, magnetic and electrical properties of Al–Ga substituted co-precipitated nanocrystalline strontium hexaferrite

“…M-type hexaferrites BaFe 12 O 19 (BaM) and SrFe 12 O 19 (SrM) with magnetoplumbite structure have extensive applications as materials for permanent magnets, highdensity recording media, telecommunication, magnetooptical and microwave devices [1,2]. The M-type hexagonal structure consists of five distinct Fe crystallographic sites, i.e.…”

Structural and magnetic properties of SrFe12O19 hexaferrite synthesized by a modified chemical co-precipitation method

“…It is a hard magnet with high coercivity, which originates from high magnetocrystalline anisotropy with single easy magnetization axis. It has been recognized that it can be used as permanent magnets, recording media, telecommunication, and as components in microwave, higher-frequency, and magnetooptical devices [5][6][7][8][9][10][11].…”

Synthesis and Characterization of PEG-Sr Hexaferrite by Sol–Gel Conversion

“…have extensive applications as promising materials for permanent magnets, high density recording media, telecommunication, magneto-optical and microwave devices, silent rooms, radar systems and military applications [1,2]. The M-type hexagonal structure has five distinct Fe crystallographic sites, namely three octahedral (2a, 12k and 4f2), one tetrahedral (4f1) and one trigonal bipyramid (2b) [3].…”
