Band–gap reduction of aluminum substituted M−type hexagonal ferrite to study its characteristics

Results in Chemistry, 2023
The sol-gel auto-combustion approach was used to create a binary combination of Strontium aluminum chromium M−type hexaferrites at the iron site. The hexagonal phase and normal composition of prepared substances were confirmed through X-ray diffraction ...

Magnetic and Terahertz–Infrared Properties of Nanodispersed Hexaferrite Sr_xBa_(1−x)Fe₁₂O₁₉ Solid Solutions

Crystals, 2023
Hexagonal ferrites with the formula SrxBa(1−x)Fe12O19 (x = 0; 0.3; 0.5; 0.7; and 1) were prepared using the citrate method. The main feature of this synthesis is a relatively low calcination temperature of 700 °C.

Multiferroic hexagonal ferrites (h-RFeO$_3$, R=Y, Dy-Lu): an experimental review [PDF]

, 2014
Hexagonal ferrites (h-RFeO$_3$, R=Y, Dy-Lu) have recently been identified as a new family of multiferroic complex oxides. The coexisting spontaneous electric and magnetic polarizations make h-RFeO$_3$ rare-case ferroelectric ferromagnets at low ...

Coercivity Enhancement of Hexagonal Ferrites

Solid State Phenomena, 2013
Hexagonal ferrites have been widely used as permanent magnets since their discovery in the 1950s. In spite of their relatively modest magnetic properties, ferrite magnets still show the best performance-to-cost ratio and different investigators are trying to improve their magnetic capabilities by using different synthesis methods and compositions ...
