Co_xFe_3-xO₄薄膜的湿法制备及性能

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)O₄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。

Abstract: The way of preparing Co_xFe_3-xO₄ films in aqueous solution was suggested It was found that Co_xFe_3-xO₄ films with different contents of Co could be formed quickly on PET, glass and Cu substrates 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 in the films and magnetic properties were stable after exposure to 60℃/90%RH for 14 days.
