【摘要】：采用磁控濺射方法在玻璃襯底上制備了不同厚度的FePd合金薄膜。利用X射線(xiàn)衍射(XRD),能譜(EDS)和物理性能測(cè)試研究了薄膜厚度對(duì)結(jié)構(gòu)和磁性能的影響。結(jié)果表明,在FePd合金薄膜中有序化過(guò)程發(fā)生在更厚的薄膜中。隨著薄膜厚度從d=22.5 nm增加到d=67.5 nm,面內(nèi)矯頑力剛開(kāi)始急劇增大,然后隨著薄膜厚度的進(jìn)一步增加矯頑力會(huì)減小。在d=67.5 nm時(shí)面內(nèi)矯頑力最大約為3.2×79.6kA/m。
[Abstract]:FePd alloy thin films of different thickness were prepared on glass substrates by magnetron sputtering. The effect of thickness on the structure and magnetic properties was investigated by X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) and physical properties. In FePd alloy films, the ordering process occurs in the thicker films. As the thickness of the films increases from 22.5 nm to 67.5 nm, the in-plane coercivity increases sharply. Then the coercivity decreases with the increase of film thickness, and the maximum in plane coercivity is about 3.2 脳 79.6 Ka / m at 67.5 nm.
