Identifikasi anomali magnetik di daerah prospek panasbumi Arjuna - Welirang = Identification of magnetic anomalies on the geothermal prospects area Arjuna-Welirang

Pengolahan data magnetik menghasilkan nilai magentik total yang telah dikoreksi oleh koreksi IGRF, Variasi Harian dan Koreksi Drift. Hasil pengolahan data kemudian diplot menjadi kontur anomali magnetik pada software SURFER 9.0. Dari kontur inilah kemudian didapatkan indikasi anomali magnetik pada data pengukuran. Anomali inilah yang nantinya akan dijadikan patokan untuk...

Synthesis, characterization, and photocatalytic activity of fe3O4@zno nanocomposite

A magnetic Fe3O4@ZnO nanocomposite (NC) was successfully synthesized by a wet milling method using a high energy milling (HEM) machine. The magnetic Fe3O4@ZnO NC was characterized by an X-ray Diffractometer (XRD), scanning and transmission electron microscopes (SEM and TEM), and a vibrating sample magnetometer (VSM). X-ray diffraction results show that...

Magnetic and microwave absorption characteristics of ti2+-mn4+ substituted barium hexaferrite

Series of Ti2+-Mn4+ ions substituted BaFe12-2xTixMnxO19 samples with x = 0.0–0.8 have been studied to find out the effect of ion substitution on their microstructure, magnetic, and microwave absorption characteristics. The materials were synthesized through the mechanical alloying process. X-ray diffraction pattern for all sintered samples confirmed that the materials...

Absorption characteristics of the electromagnetic wave and magnetic properties of the la0.8ba0.2fexmn½(1-x)ti½(1-x)o3 (x = 0.1–0.8) perovskite system

This paper reports on the magnetic properties and electromagnetic characterization of La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8). The La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8) materials were prepared using a mechanical alloying method. All the materials were made of analytical grade precursors of BaCO3, Fe2O3, MnCO3, TiO2, and La2O3, which were blended and mechanically milled...
