Abstract:Recently, we have developed a synthetic MFM tip consisting of two ferromagnetic layers and a non-magnetic spacer [1]. The two ferromagnetic layers are coupled antiferromagnetically so that the MFM works in a differential detection mode. This has led to the enhancement of high-frequency component against the lower frequency counterpart. Experimentally we have also found that the synthetic tip functions as a point-dipole tip. In this paper, we will present a detailed theoretical analysis of the tip and compare the results with experimental data. The effect of spacer thickness on the imaging characteristics of the MFM tip will also be discussed. [1] Y. H. Wu et al, Appl. Phys. Lett. 82, 1748-1750 (2003).
