摘要: We investigated structural and magnetic properties of the easy-axis aligned $L{1}_{0}$-FePt nanoparticles by combined use x-ray diffraction (XRD), magnetization, $^{57}\text{F}\text{e}$ M\"ossbauer measurements. The were fixed in a polystyrene matrix performing free radical polymerization styrene under an aligning external field. spectrum nanoparticles/polystyrene composite showed tremendous decrease second fifth absorption lines condition that incident $\ensuremath{\gamma}$ ray was parallel to This result indicates easy axes have strong preferred orientation with finite distribution. estimated distribution using hyperfine parameters, which is good agreement determined XRD rocking curve.
