“…[10][11][12] Some reports have found the doping effect in iron oxide, and magnetic parameters, such as permeability or saturation magnetization, were improved by doping with B 2 O 3 , Co, or Zn ions. 13,14 In this report, Zn-doped MnFe 2 O 4 nanoparticles were prepared, Zn content was varied, and composition dependence was first examined by dc and ac magnetization measurements. Based on the results, heating efficiency was obtained for magnetic hyperthermia treatments.…”

Mn-Zn ferrite, Mn1−xZnxFe2O4 nanoparticles encapsulated in amorphous SiO2 were prepared using our original wet chemical method. X-ray diffraction patterns confirmed that the diameters of these particles were within 7–30 nm. Magnetization measurements for various sample compositions revealed that the saturation magnetization (Ms) of 7 nm particles was maximum for the x = 0.2 sample. AC magnetic susceptibility measurements were performed for Mn0.8Zn0.2Fe2O4 (x = 0.2) samples with 13–30 nm particles. The peak of the imaginary part of the magnetic susceptibility χ″ shifted to higher temperatures as the particle size increased. An AC field was found to cause the increase in temperature, with the 18 nm particles exhibiting the highest temperature increase, as expected. In addition, in vitro experiments were carried out to study the hyperthermia effects of Mn1−xZnxFe2O4 (x = 0.2, 18 nm) particles on human cancer cells.

“…Among these methods, Chemical co-precipitation was selected as a best method to synthesize nanoparticles. It is least expensive simplest approach for making nanoparticles, it produce large quantities (order of grams) in relatively short interval of time [14]. P.R.Arjunwadkar et al studied the influence of Al 3+ on lithium ferrite prepared by chemical method, he reported that increasing Al 3+ magnetization and the retentivity decreased.…”

“…Tipe MnZn ferrite merupakan jenis magnet berbasis ferrite yang banyak dikembangkan dan diaplikasikan untuk industri [1][2][3][4] ferrite banyak disukai karena memiliki nilai permeabilitas dan saturasi magnetik, serta temperatur Curie yang tinggi [5]. Studi karakteristik yang dilakukan selama ini lebih banyak ditujukan untuk mempelajari efek magnetostrictive yang merupakan salah satu sifat paling menentukan dalam aplikasi berbasis magnet maupun mekanisme penumbuhan serta pergerakan butir pada MnZn ferrite [6][7][8][9]. Sementara studi karakteristik termal yang penting untuk mengetahui pengaruh rasio serta jumlah penambahan Mn dan Zn terhadap temperatur pembentukan ferrite belum banyak dilakukan.…”

IntisariMnZn ferrite merupakan salah satu jenis magnet berbasis ferrite yang banyak dikembangkan dan diteliti karena performa sifat magnetiknya yang relatif lebih baik dibandingkan dengan magnet berbasis ferrite lainnya. Studi yang banyak dilakukan selama ini untuk mengetahui karakteristik magnetik maupun elektrik MnZn ferrite. Paper ini membahas karakteristik termal MnZn ferrite yang menggunakan material teknis dari industri magnet di Indonesia. Material awal berupa MnO, ZnO, dan F e2O3 dikomposisikan untuk membentuk MnxZn1−xFe2O4 dengan variasi x = 0,2; 0,35; 0,65; 0,8. Komposisi tersebut dicampur menggunakan High Energy Milling selama 10 menit. Sampel hasil pencampuran diuji karakteristik termalnya (temperatur kamar hingga 900• C) menggunakan prototipe Differential Thermal Analyzer (DTA) buatan Pusat Penelitian Fisika -LIPI. Hasil pengujian menunjukkan peningkatan energi total reaksi endotermik dengan meningkatnya rasio Mn terhadap Zn dalam campuran ferrite. Hasil pengujian juga menunjukkan terjadinya fasa antara pada rasio Mn : Zn = 0,65 : 0,35 yang ditunjukkan dengan munculnya puncak endotermik tambahan. Peningkatan rasio Mn terhadap Zn akan meningkatkan energi total reaksi dan mengakibatkan pergeseran nilai temperatur transformasi fasa. ABSTRACTMnZn ferrite is one type of ferrite based-magnet which is largely developed and studied due to its better magnetic properties performance compared to other ferrite based-magnet. The extensive recent study of MnZn ferrite mostly was conducted to examine its magnetic and electric properties. This paper will discuss thermal characteristics of MnZn ferrite, which was obtained from technical/industrial raw material of magnet industry in Indonesia. The initial raw material, consist of MnO, ZnO, and F e2O3, was composed into MnxZn1−xFe2O4 ferrite with x = 0.2; 0.35; 0.65; 0.8. Those composition were then pre-mixed using High Energy Milling for 10 minutes. The as-mixed samples were then characterized using DTA prototype made by Research Center for Physics -LIPI from room temperature to 900• C. The characterization results show the increase of endothermic reaction total energy by increasing Mn to Zn ratio in ferrite mixture. They also infer the formation of intermediate phase at Mn to Zn ratio of 0.65:0.35, which is represented by the appearance of new endothermic peak. It can be concluded that the increase of Mn to Zn ratio gives the increase of total reaction energy and the shifting of phase transformation temperature.
