摘要

本研究合成了Mg2+、Sn4+、Cu2+共掺杂的YIG铁氧体，表征为Y3Fe4.8-xMgxCu0.1Sn0.1O12。结构表征表明，掺杂剂有效地掺入YIG晶格，占据八面体a位，取代Fe3+离子，扩展晶格。磁性能随Mg2+水平的变化而变化：饱和磁化强度在33.42 emu/g时达到峰值（x = 0.20），铁磁共振线宽在30 Oe时达到最小（x = 0.15）。渗透率在x = 0.15时达到峰值。介电常数随Mg2+浓度的增加而增加，但介电损耗保持在较低水平。本研究为高性能YIG铁氧体的小型化和集成化提供了一种策略。

Synergistic effects of Mg2+, Sn4+, and Cu2+ co-doping on the magnetic and dielectric properties of yttrium iron garnet ferrites

In this research, YIG ferrite co-doped with Mg²⁺, Sn⁴⁺, and Cu²⁺, represented by Y₃Fe_4.8-xMg_xCu_0.1Sn_0.1O₁₂, was synthesized. Structural characterization showed effective incorporation of dopants into the YIG lattice, and occupying the octahedral a-sites, replacing Fe³⁺ ions, and expanding the lattice. Magnetic properties varied with Mg²⁺ levels: saturation magnetization peaked at 33.42 emu/g (x = 0.20), and the ferromagnetic resonance linewidth was minimized at 30 Oe (x = 0.15). Permeability peaked at x = 0.15. Dielectric constant increased with Mg²⁺ concentration, while dielectric loss remained low. This study provides a strategy for high-performance YIG ferrites for miniaturization and integration.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
