) were prepared using a sol--gel technique. XRD patterns confirm their single phase Aurivillius structure, and the corresponding powder Rietveld analysis indicates the change of space group around

x = 0.12

. The magnetic hysteresis loops are obtained and ferromagnetism is therefore confirmed in BFCT-

x

thin films. The remanent magnetization (

M_{r}

) first increases and reaches the maximum value of 0.42 emu/cm

^{3}

at

x = 0.12

due to the possible Fe

--O--Co

^{3 +}

ferromagnetic coupling. When

x = 0.25

, the

M_{r}

increases again because of the dominant Fe

^{3 +}

--O--Co

^{3 +}

ferromagnetic coupling. The remanent polarization (

2 P_{r}

) of BFCT-0.25 was measured to be as high as 62

μ

C/cm

^{2}

, a 75% increase when compared with the non-doped BFCT-0 films. The

2 P_{r}

remains almost unchanged after being subjected to

5.2 \times 10^{9}

read/write cycles. Greatly enhanced ferroelectric properties are considered to be associated with decreased leakage current density.
