Morphology and Magnetic Properties of Hexagonal Ferrite Sr₁₋ₓMₓFe₁₂₋ₓZnxO₁₉ (M= La, Dy, Nd, Yb) [PDF]

, 2003
A permanent magnet in the form of a ring or disc is one of the components in many devices. In this project, hard magnetic ferrite with formula Sr₁₋ₓMₓFe₁₂₋ₓZnxO₁₉ (x= 0.1, 0.3, 0.5, 0.7, 0.9) (M= La, Nd, Dy, Vb) is used because of the low cost, high ...

Facile synthesis of hexagonal strontium ferrite nanostructures and hard magnetic poly carbonate nanocomposite

Main Group Metal Chemistry, 2017
Hard magnetic SrFe12O19 (SrFe) nanostructures were synthesized via a facile sol–gel procedure. The effects of temperature concentration and different capping agents on the particle size and morphology of the magnetic nanoparticles were investigated.

Iron oxide doped boron nitride nanotubes: structural and magnetic properties

, 2010
A first-principles formalism is employed to investigate the interaction of iron oxide (FeO) with a boron nitride (BN) nanotube. The stable structure of the FeO-nanotube has Fe atoms binding N atoms, with bond length of roughly $\sim$2.1 \AA, and binding ...
