A method of manufacturing the same, magnet and magnetic composition and L10 type FeNi alloy particles

摘要

And to provide a process for the production of L1 _0-type iron-nickel alloy particles. Step (1) preparing a liquid dissolved and dispersed in a solvent and / or iron-containing compounds, a protective polymer and nickel-containing compounds, the liquid obtained, is contained in the nickel-containing compounds and iron ions contained in the iron-containing compound by heating in a hydrogen atmosphere the precursor particles preparing a precursor particles by adding a reducing agent for nickel ions, containing nickel and iron (2), and reducing the precursor particles, and I (3) a step of ordering the L1 _0-type structure of the alloy particles. The lattice constant of the alloy particles obtained by the analysis of the XRD pattern and, in the range of 1~200000nm average particle size, L1 _0-type iron-nickel alloy is in the range a = 2.520~2.546Å, the c = 3.564~3.600Å I will provide particles. To provide a magnet and magnetic composition.
