Sintered ferrite (ceramic) magnets are also available in forms of isotropic and an-isotropic. The magnetic properties of isotropic ferrite are the same in all directions, therefore they can be magnetized in any pole arrangements. An-isotropic ferrite magnets, on the other hand, can only be magnetized in the direction they are oriented during production, but they have much higher magnetic strength than isptropic ones.
The most common hard ferrites are:
Strontium ferrite, SrFeO (SrO·6FeO), used in small electric motors, micro-wave devices, recording media, magneto-optic media, telecommunication and electronic industry.
Barium ferrite, BaFeO (BaO·6FeO), a common material for permanent magnet applications. Barium ferrites are robust ceramics that are generally stable to moisture and corrosion-resistant. They are used in e.g. loudspeaker magnets and as a medium for magnetic recording, e.g. on magnetic stripe cards.
Cobalt ferrite, CoFeO (CoO·FeO), used in some media for magnetic recording.
