Abstract

Telah disintesis material magnet barium heksaferit tipe-M dengan substitusi ion Co-Ni terhadap Fe, BaFe12-2xCoxNixO19 (x = 1). Material barium heksaferit disintesis di atas substrat melalui metode Ultrasonic Spray Pyrolysis yang dibuat dengan variasi jumlah lapisan 1, 2 dan 3. Selanjutnya, diberi perlakuan panas berupa sintering 10000C selama 1 jam. Analisa mengenai struktur kristal dan sifat magnetik material dikarakterisasi menggunakan alat X-ray Diffraction (XRD) dan Vibrating Sample Magnetometer (VSM). Hasilnya menunjukkan bahwa pertambahan jumlah lapisan menyebabkan penurunan ukuran kristal dan nilai medan koersivitas (Hc). Selain itu, nilai medan koersivitas mengalami penurunan akibat substitusi ion Co-Ni dan menjadikan material ini bersifat soft magnetic. M-type Barium Hexaferrite magnetic material has been synthesized by the substitution of Co and Ni into Fe, BaFe12-2xCoxNixO19 (x = 1). Barium Hexaferrite magnetic material on the substrate synthesized via ultrasonic spray pyrolysis method by variation number of layers 1,2 and 3. Then, sample were sinterred at 10000C for 1 hour. The crystal structure and magnetic properties were characterized using X-ray diffraction (XRD) and vibrating sample magnetometer (VSM), respectively. The results showed that the crystalline size and the coercivity (Hc) decrease with increasing number of layers. Moreover, the coercivity decrease by Co-Ni substitution and the material leads to a soft magnetic.
