【摘要】 提出了在碱性溶液中通过加入添加剂在涤纶（ＰＥＴ），玻璃，铜片等基体上快速制备Ｃｏ－ｘＦｅ＿（３－ｘ）Ｏ＿４磁性薄膜的方法。实验结果表明，湿法制备的薄膜具有多晶的尖晶石结构，随着Ｃｏ含量的增高，矫顽力逐渐增大，耐蚀性良好。更多还原

【Abstract】 The way of preparing Co_xFe_3-xO₄ films in aqueous solution was suggested It was found thatCo_xFe_3-xO₄ films with different contents of Co could be formed quickly on PET, glass and Cu sub-strates by adding suitable additives to the solution The films were of poloycrystalline-spinel structure,with no preferred orientation The coercive forces were increased with the increase of Co contents inthe films and magnetic properties were stable after exposure to 60℃/90%RH for 14 days;更多还原
