| 英文摘要 | A polycrystalline AlN underlayer prepared by reactive sputtering has been used for the preparation of SmCo3.5Cu0.5 thin films with varying thickness. The out-of-plane (OOP) texture is confirmed by X-ray diffraction and magnetic measurements. A highest ambient coercivity of 2.92 T is obtained with good squareness. The microstructure shows columnar grains and a high density of stacking faults. Additionally, a twinning structure is found. The thermal stability of the coercivity of AlN-buffered SmCo3.5Cu0.5 thin films has been investigated in correlation with the microstructure. The present work demonstrates the great potential of using AlN underlayer for the preparation high-performance Sm-(Co, Cu) thin films with OOP texture. (C) 2017 Elsevier B.V.
