Abstract

It is shown that the magnetic properties, structure, and residual stress of Fe films electrodeposited from iron (II) chloride solution are strongly dependent on electrodeposition conditions such as the applied current density and solution temperature. The applied current was varied from 5 to 100 mA/cm2, and the solution temperature was also varied from 20°C to 60°C. Under these conditions, lower coercive forces were obtained at lower current densities and higher solution temperatures, and it appeared that the residual stress was the dominant factor in the magnetic properties of the films. The value of the Q factor of a coil composed of Cu wire coated with these Fe films was measured; the Q factor was found to vary over the range of deposition conditions studied, and was dependent on the coercive force.
电沉积铁膜的磁性能与结构
结果表明,用氯化铁(II)溶液电沉积Fe膜,其磁性能、结构和残余应力与电沉积条件(如外加电流密度和溶液温度)密切相关。施加的电流在5至100mA/cm2之间变化,溶液温度也在20°C至60°C之间变化。在这些条件下,在较低的电流密度和较高的溶液温度下获得了较低的矫顽力,并且残余应力似乎是影响薄膜磁性的主要因素。测量由涂覆有这些Fe膜的Cu线组成的线圈的Q因子的值;发现Q因子在所研究的沉积条件范围内变化并且取决于矫顽力。
