FeNi films of different thickness and FeNi/(Fe, Co)/FeNi trilayers were prepared by magnetron sputtering deposition onto glass substrates. The permalloy films had a columnar microstructure. The detailed analysis of the magnetic properties based on the magnetic and magneto-optical measurements showed that at thicknesses exceeding a certain critical thickness, hysteresis loops acquire a specific shape and the coercive force of the films increase sharply. The possibility of the estimation of the perpendicular magnetic anisotropy constant using the Murayama equation for the thickness dependence of saturation field was demonstrated. The results of studies of the structural and magnetic properties of FeNi films laminated by Fe and Co spacers with different thickness are presented.
通过磁控溅射沉积在玻璃基板上制备了不同厚度的FeNi薄膜以及FeNi/(Fe, Co)/FeNi三层膜。坡莫合金薄膜具有柱状微观结构。基于磁性和磁光测量对磁性进行的详细分析表明,当厚度超过某个临界厚度时,磁滞回线呈现出特定形状,并且薄膜的矫顽力急剧增加。证明了利用村山方程根据饱和场的厚度依赖性来估算垂直磁各向异性常数的可能性。给出了用不同厚度的Fe和Co间隔层层压的FeNi薄膜的结构和磁性研究结果。
