We investigated the quaternary Cu-25.49%Zn-7.68%Al-3.44%Ni and Cu-26.03%Zn-6.31%Al-2.73%Mn (wt. %) alloys according to their structural and magnetic properties. For structural observations, we employed X-ray diffraction (XRD), scanning electron microscope (SEM), and electron dispersion spectroscopy (EDS) techniques to study. The magnetic properties of alloys were characterized as a function of temperature (T) and applied external magnetic field (H) by using Physical Properties Measurement System (PPMS) magnetometry. According to SEM and XRD observations, the existing microstructures consist of two types of precipitates that are namely α and intermetallic κ-phases in CuZnAlNi alloy. We also observed the austenite phase in CuZnAlMn alloy. The M-H magnetization curves exhibited obvious paramagnetic behavior for the examined alloys. Although Ni and Mn elements have similar magnetic nature, they show different magnetic characteristics with different structures.

我们根据结构和磁性能研究了四元 Cu-25.49%Zn-7.68%Al-3.44%Ni 和 Cu-26.03%Zn-6.31%Al-2.73%Mn (wt.%) 合金。对于结构观察，我们采用 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和电子色散光谱 (EDS) 技术进行研究。合金的磁性能被表征为温度 ( T ) 和外加磁场 ( H) 通过使用物理特性测量系统 (PPMS) 磁力计。根据 SEM 和 XRD 观察，现有的显微组织由两种类型的析出物组成，即 CuZnAlNi 合金中的 α 相和金属间 κ 相。我们还观察到 CuZnAlMn 合金中的奥氏体相。MH 磁化曲线对所检测的合金表现出明显的顺磁行为。尽管Ni和Mn元素具有相似的磁性，但它们以不同的结构表现出不同的磁特性。
