When barium ferrite magnets increase in temperature, their high intrinsic coercivity improves, this is what makes it more resistant to thermal demagnetization.

Ferrite magnets are extremely good insulators and don't allow any electrical current to flow through them and they are brittle which shows their ceramic characteristics.

Barium ferrite completely out classes metal particles, mostly because Ba‑Fe is already in its oxidized state and so is not restricted in its size by a protective coating.

Earlier media devices utilized doped acicular oxide materials to yield the coercivity values necessary to record.

ID cards using barium ferrite are made with a magnetic fingerprint that identifies them, allowing readers to self-calibrate.

The materials can be formed into almost any shape and size using a process called sintering, whereby powdered barium ferrite is pressed into a mold, and then heated until it fuses together.

[13] Barium ferrite is used for enterprise level[14] and commodity linear tape-open (LTO) tape storage media.

Because of its high density, barium ferrite has led to data capacity improvements in both enterprise and LTO tapes over prior metal particle (MP) media technology.
