“…This ferromagnetic behavior in the nanoparticles is due to the presence of oxygen vacancies in BiFeO 3 system [41,47]. Enhancement of magnetic as well as dielectric properties in BiFeO 3 can be achieved by adding doping of Mn, Ni, Pb, Ti, Sr, and Zn [48][49][50][51][52][53][54][55][56]. Up to the present, there have been various studies examining the doping effects of BiFeO 3 nanoparticles with numerous advanced techniques to improve their performance.…”

Ferrite-based nanoparticles, namely, bismuth ferrite (BiFeO 3 ) and calcium ferrite (CaFe 4 O 7 ), have been synthesized via sol-gel and chemically dissolved method, respectively, employing hematite (α-Fe 2 O 3 ) as the Fe 3+ ion source. Firstly, α-Fe 2 O 3 nanoparticles were prepared from natural iron sand containing mostly magnetite (Fe 3 O 4 ) phase through coprecipitation technique continued by sintering process at 800°C for 2 h. Higher BiFeO 3 phase content was achieved after Bi-Fe gel being annealed at 650°C for 1 h in air atmosphere. Furthermore, major phase of CaFe 4 O 7 was formed with molar ratio of Fe 3+ /Ca 2+ = 6 and sintering temperature of 800°C for 3 h. Interestingly, the powders with dominant CaFe 4 O 7 phase, known as calcium biferrite, exhibit higher ferromagnetism at room temperature. The magnetic properties of the calcium biferrite are comparable to those of barium hexaferrite which can be applied for radar-absorbing material. Meanwhile, BiFeO 3 powders also show weak room temperature ferromagnetism. It has also demonstrated that Ni doping in the bismuth ferrite (BiFe 1− xNi x O 3 with x = 0.1) nanoparticles results in enhancement of the magnetic properties. Moreover, a ferroelectric hysteresis loop and a trend of frequency dependence of the dielectric constant have been observed, which were enhanced by Pb doping (Bi 1− yPb y FeO 3 with y = 0.1). These results suggest a multiferroic behavior in the BiFeO 3 nanoparticles.

A large eruption of Mount Gamalama happened nearly 350 years ago has left the frozen lava rocks that are now spread in the form of black stone located in the North-East coast of the island of Ternate, called batu angus (Angus stone). This paper reports the basic analysis including the phase content, crystal structure and particle morphology of the frozen lava rock, Angus stone, briefly. Based on the XRD pattern, Angus stone contains up to 20% of magnetic phases. The analysis of XRF and XRD data reveals that there are dominantly non-magnetic phases (silicate phases) in the Angus stone with the combination of Si-Al-K-Ca-O elements. Elemental distribution map from SEM/EDX image shows that there is a clear separation between non-magnetic and magnetic phases in the crushed powders indicating the easiness to obtain both phases separately. This study proves that Angus stone has potential application as a base material for the preparation of magnetic and non-magnetic functional materials.
