通过电沉积方法在室温下制备了具有纳米结构组织的Nd-Fe-Co-Ni-Mn高熵合金磁性薄膜.通过改变电沉积参数,如沉积电位、沉积时间,可控制薄膜的纳米结构及表面形貌.扫描电子显微镜观察结果表明,在Ti基体上,-2.2V下沉积5 min可制备出大小在200 nm左右的均匀分布的球形颗粒薄膜,延长沉积时间会使薄膜变得更加致密,而沉积电位的负移会导致纳米片的出现.能谱结果表明5种元素发生了共沉积,结构分析表明该薄膜是无定形态的.稀土元素Nd与过渡金属发生共沉积,可能是由于过渡金属离子与二甲基亚砜形成多核配位化合物而使得过渡金属离子沉积电位负移所致.Nd-Fe-Co-Ni-Mn高熵合金薄膜在室温下具有良好的软磁性能.
