Nanopartikel Fe3O4 yang berasal dari pasir besi pantai Glagah Kulon Progo telah berhasil disintesis menggunakan metode kopresipitasi dengan berbagai variasi konsentrasi HCl (10%, 15%, 25% dan 37%). Pengaruh konsentrasi HCl terhadap mikrostruktur dan sifat kemagnetan dari Fe3O4 dilihat dengan menggunakan XRD, SEM & EDX serta VSM. Hasil XRD menunjukkan bahwa Fe3O4 yang dihasilkan memiliki struktur kristal kubik invers spinel. Semakin besar konsentrasi HCl, semakin baik derajat kristalinitasnya. Hasil SEM & EDX untuk sampel Fe3O4 dengan konsentrasi HCl 37% menunjukkan ukuran butir (grain) yang hampir sama serta tingkat kemurnian sampel Fe3O4 yang dihasilkan sebesar 100% (Fe 72,42% dan O 27,58%). Hasil VSM menunjukkan Fe3O4 hasil sintesis memiliki sifat superparamagnetik serta bersifat soft magnetic. Nanopartikel Fe3O4 dengan konsentrasi HCl 25% memiliki Hc, Mr dan Mmax masing-masing sebesar 0,0215 T, 11,60 emu/gr dan 36,51 emu/gr. Sedangkan Nanopartikel Fe3O4 dengan konsentrasi HCl 37% memiliki Hc dan Mr yang lebih kecil yaitu masing-masing sebesar 0,0017 T dan 10,83 emu/gr serta Mmax yang lebih besar yaitu 36,82 emu/gr.References
