Abstract
The low-temperature deposition of BaNi(2-x)CoxFe16O27 thin films with a Ba hexaferrite structure for electromagnetic shielding was studied. The BaNi(2-x)CoxFe16O27 thin films produced through the spin spray process were suitable for thin film deposition on a flexible substrate because it crystallized well at low temperature below 90℃. The change in shielding characteristics depending on the Co content of the BaNi(2-x)CoxFe16O27 thin film was investigated, and excellent shielding characteristics with S21 of -1 dB were obtained in a wide frequency range of 26~40 GHz when the Co content was 0.4 or more. The purpose of this study is to analyze changes in shielding properties caused by change in Co content in relation to phase changes in BaNi(2-x)CoxFe16O27 and obtain basic data for developing excellent flexible electromagnetic wave shielding materials.
