Ihe ndọta ferrite siri ike bụ nke magnet na-adịgide adịgide, nke bụ otu n'ime ihe ndọta a na-ejikarị eme ihe ugbu a, ọnụ ahịa ya dịkwa obere.A na-eme magnetik Ferrite nke SrO na Fe2O3 dị ka isi akụrụngwa, ma na-eme ya site na seramiiki sintering.Ihe dị iche na ndọta ndị ọzọ na-adịgide adịgide bụ na ferrite abụghị nke magnetik na-adịgide adịgide n'ụwa.

Na mgbakwunye, enwere ụdị magneti ferrite abụọ, isotropic na anisotropic.Isotropic ferrite magnet pụtara na ọ dịghị eriri igwe maka magnetization n'oge ịkpụzi na ịpị, na magnetization ntụziaka na-ekpebisi ike.Ya bụ, mgbe magnetik gwụchara, enwere ike ịmegharị ha n'akụkụ niile.Anisotropic ferrite magnet pụtara na a na-ekpebi magnetization na eriri igwe mgbe a na-akpụzi na ịpị, ya bụ, n'agbanyeghị otú e si magnetize ha, ntụziaka magnetization abụghị mgbanwe.
