Physics-based modeling of cobalt-doped nickel-zinc on-chip ferrite inductors

Bambang Mulyo Raharjo, Dicky Rezky Munazat, Sudirman Rohadi

The miniaturization of integrated voltage regulators (IVRs) for multi-core processors is fundamentally bottlenecked by the high-frequency magnetic losses of conventional inductor cores. This study presents a rigorous computational framework to optimize Cobalt-doped Nickel-Zinc ferrite (Ni_(1-x) Zn_0.4 Co_x Fe_2 O_4) for 10 MHz …

Neutron Diffraction Investigation of Structure and Magnetic Properties Near the Transition Temperature in La0.7Ca0.2-x□xSr0.1MnO3 (x = 0.05 - 0.01)

Dr Budhy Kuniawan, Dr Ivan da Silva Gonzalez, Mr Kuldeep Singh Chikara, Miss Okvarahireka Vitayaya et autres

We propose temperature-dependent neutron diffraction measurements on La0.7Ca0.2-x xSr0.1MnO3(x = 0.05 - 0.10) to investigate the evolution of magnetic and structural properties near the Curie temperature (TC). Cation deficiency ( ) in hole-doped manganites introduces Mn2+ alongside Mn3+ and Mn4+, leading to …

Probing Defect-Induced Magnetism in ZnO Nanoparticles via Small Angle Scattering of Polarized Neutron (SANSPOL) and Soft X-ray Techniques

Suci Winarsih, Dicky Rezky Munazat, Mrs Evelyn Pratami Sinaga, Dr Liszulfah Roza et autres

ZnO nanoparticles exhibit room-temperature ferromagnetism (RTFM), primarily driven by surface oxygen vacancies and structural defects, rather than magnetic doping. In our recent study, we observed magnetic hysteresis at 2 K in both Co- and Al-doped ZnO nanoparticles, with Al-doped ZnO showing magnetic …

Inelastic Neutron Scattering Studies on Complex Magnetic Ground State in Alkali-Doped Nd0.7Sr0.25A0.05MnO3 (A = Na, K)

Dr Maykel Manawan, D. T. Adroja, Djati Handoko, Dr Budhy Kuniawan et autres

Alkali-doped Nd0.7Sr0.25A0.05MnO3 (A = Na, K) perovskites exhibit a non-saturating magnetisation that peaks at 145 K, signalling a complex magnetic ground state beyond canonical double-exchange, so we request 48 h on MARI to perform multi-E inelastic neutron scattering (60, 17.8, 8.2 meV, …

Degradation of impurity-induced superconducting transition in sol-gel synthesized Y-Ba-Cu-O ceramics

Juan De Bebetho, Alvin Wihono, Nabila Shananda, Budhy Kurniawan et autres

YBa2Cu3O7 (Y-123) high-temperature superconductor was synthesized using a nitrate-citrate (NC)-based solgel method and sintered at 950 degrees C to investigate the relationship between phase composition and electrical transport properties. X-ray diffraction with the Rietveld refinement confirmed the predominant formation of the orthorhombic …

Electrical Resistivity and Magnetoresistance Properties of Cation A-site substitution in La0.8-xAgxCa0.2MnO3 (x = 0.1 and 0.15)

Dicky Rezky Munazat, Budhy Kurniawan, Maykel T. E. Manawan, Agung Imaduddin

The polycrystalline sample of La0.8-xAgxCa0.2MnO3 (x = 0.1 and 0.15) has been successfully synthesized using a sol-gel method in our previous work. Here, we have investigated the electrical resistivity and magnetoresistance of both samples. All samples exhibited metallic behavior, as evidenced by …

Microstructure and Magnetic Properties of LaMnO3 Coatings via Electrophoretic Deposition

Gede Yudharma, Budhy Kurniawan, Dicky Rezky Munazat

This study investigates the microstructural and magnetic properties of LaMnO3 coatings fabricated by electrophoretic deposition (EPD) on stainless steel substrates. LaMnO3 powders were synthesized using a sol-gel citrate-nitrate auto-combustion method. The LaMnO3 suspension was diluted to 30 mg/50 ml using a mixture …
