XRD profiles (Y offset by 3000) and UV-vis spectra for ttb-CuPc films ((a) and (c)) and after CoFe deposition ((b) and (d)).
(a) Normalized magnetic hysteresis loops for glass/ttb-CuPc(n ML)/CoFe(5 nm), where the open scatters indicate the experiment data and solid lines show fitting results. (b) shows ttb-CuPc thickness dependence of Hc and S for ttb-CuPc(n ML)/CoFe(5 nm) films. The inset of Fig. 2(b) gives an example of magnetic block for sample ttb-CuPc(3ML)/CoFe. And (c) summarizes the calculated averaged granule radius r and SPM contribution for samples with different ttb-CuPc thickness.
I-V cures for ttb-CuPc(n ML)/CoFe(5 nm): (a) without and (b) with magnetic field.
