Abstract


Sintesis Barium M-Heksaferrit (BaFe11,4Zn0,6O19) doping ion Zn telah dilakukan dengan metode kopresipitasi. Bahan yang digunakan dalam sintesis yaitu BaCO­3, FeCl3.6H2O dan ion Zn. Dalam penelitian ini digunakan variasi suhu kalsinasi pada temperatur rendah yaitu 80oC, 150oC, 200oC dan 280oC selama 4 jam. Hasil sintesis dikarakterisasi dengan DSC-TGA (Differential Scanning Calorimetry – Thermogravimetric), XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy) dan VSM (Vibrating Sample Magnetometer). Barium M-Heksaferrit terbentuk pada temperatur 150oC sebesar 72,54% dan mempunyai ukuran partikel sebesar 0,5μm. Kurva histerisis menunjukkan telah terbentuk softmagnetic dengan magnetisasi remanensi (Mr) sebesar 0,01 emu/gr, medan koersivitas (Hc) sebesar 0,00825 Tesla dan mempunyai magnetisasi tertinggi terjadi ketika medan koersivitas (Hc) sebesar 1 Tesla dengan magnetisasi sebesar 0,55 emu/gr.
