Sol–Gel Route for the Synthesis of CoFe2–xErxO4 Nanocrystalline Ferrites and the Investigation of Structural and Magnetic Properties for Magnetic Device Applications

“… 1 , 2 Among different magnetic materials, spinel cobalt (Co) ferrites have drawn continuous attention because of their soft ferromagnetic nature with high electromagnetic performance and exceptional physical properties. 3 , 4 The common form of the spinel ferrite structure is (A 2+ )[B 2 3+ ]O 4 2– , where the divalent A 2+ and trivalent B 2 3+ cations are occupied in the tetrahedral (A) and octahedral (B) sites. The face-centered structure of ferrite arises from the formulation of cations and oxygen anions.…”

A systematic computational study of electronic, mechanical, and optical properties of Fe1−xCox alloy

“…FeCo alloys have greater attraction due to its rich physical and chemical properties. Such as ferroelectricity at room temperature, high Curie temperature, high magnetic moments, and mechanical hardness, etc For these properties, FeCo alloy can be promoted for various technological applications for instance, transformer core, electric motor, pole-pieces, high density magnetic recording, biomedicine, drug delivery, magnetic resonance imaging, magnetic hyperthermia and specially data storage and so on [4][5][6][7][8][9][10][11]. Elasticity is the embryonic property of solid materials that is essential in numerous areas spanning of materials selection in mechanical design.…”
