Magnetic Properties of FeNi/RE Magnetic Nanomultilayer Films
Source abstract
Abstract
This paper delves into the magnetic properties of transition metal FeNi doping with heavy rare earth (RE) elements (including Gd and Nd) magnetic nanomultilayer films. Through experimental methods such as Vibrating Sample Magnetometer magnetic measurements and Ferromagnetic Resonance, the influence of rare earth element doping on the magnetic properties of FeNi alloy films is systematically analyzed. The experimental results reveal that the addition of rare earth elements significantly alters the saturation magnetization, coercivity, and magnetic anisotropy of FeNi alloys, with notable impacts on their ferromagnetic resonance behavior. This study not only provides crucial insights into the unique structures and magnetic mechanisms of rare earth-transition metal alloys but also offers theoretical support for the development of high-performance magnetic materials.
