Abstract

The unique properties of ferrimagnets including easy detection of their dynamic and static states, strong resistance to external disturbances, and rapid dynamic characteristics, have made them attractive in the spintronics community. Our study focuses on the engineering of these magnetic properties of ferrimagnets, particularly employing a GdFeCo alloy, a prominent ferrimagnetic material, by utilizing magnetron sputtering. A series of GdFeCo films are fabricated by altering their thicknesses and working pressure during the sputtering process. Our experimental results reveal that these sputtering parameters significantly influence a Gd composition within the films, which in turn affects critical properties of ferrimagnets such as magnetic anisotropy, and magnetic moment compensation temperature. By precisely controlling these sputtering parameters, we successfully tailored the magnetic properties of the GdFeCo thin films with desired properties, offering new possibilities for the creation of sophisticated magnetic materials tailored to specific technological needs.

通过溅射条件定制的钆钴合金薄膜的磁性能
铁氧体磁体具有独特的特性,包括易于检测其动态和静态状态、抗外部干扰能力强以及快速动态特性,这些特性使其在自旋电子学领域极具吸引力。我们的研究侧重于铁氧体磁性能的工程设计,特别是利用磁控溅射技术,采用钆钴合金这种著名的铁磁性材料。在溅射过程中,通过改变 GdFeCo 薄膜的厚度和工作压力,制造出一系列 GdFeCo 薄膜。我们的实验结果表明,这些溅射参数会显著影响薄膜中的钆成分,进而影响铁磁体的关键特性,如磁各向异性和磁矩补偿温度。通过精确控制这些溅射参数,我们成功地定制了具有所需特性的 GdFeCo 薄膜的磁性能,为创造出满足特定技术需求的精密磁性材料提供了新的可能性。

期刊介绍: Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
