摘要

A method for analyzing magnetic nanoparticles using Mossbauer spectroscopy, a method for producing magnetic nanoparticles using Mossbauer spectroscopy, and a magnetic nanoparticle. One embodiment of the present invention relates to a method for manufacturing a magnetic recording medium, comprising: mixing a magnetic material precursor, a surfactant, and a solvent at room temperature; A reaction step of heating the mixed solution in the mixing step to a reaction temperature and continuing the reaction for a predetermined time; Separation step of separating the pre-magnetic nanoparticles using a centrifugal separator or magnetism; And a plasma processing step of producing magnetic nanoparticles by irradiating the pre-magnetic nanoparticles with a plasma, wherein plasma processing conditions in the plasma processing step are such that the magnetic nanoparticles and the pre-magnetic nanoparticle crystal structure Wherein the spin canting angle of the magnetic nanoparticles is larger than the spin canting angle of the pre-magnetic nanoparticles with respect to the same site of the magnetic nanoparticles.
