Magnetic Resonance Imaging Mri

The effort to produce an instrument that can achieve high spatial resolution, nondestructive, surface and sub-surface imaging for a variety of materials comes with many challenges. One approach, magnetic resonance-force microscopy (MRFM), lies at the nexus of two sensitive technologies: magnetic force microscopy (MFM) and magnetic resonance imaging (MRI). MFM uses a magnetic tip in a standard atomic force microscope (AFM) to obtain magnetic information about a surface. A difference in the magnetic moments of surface atoms in different regions on the surface varies the cantilever resonance. MRI, on the other hand, uses the spin states of magnetically biased atoms to differentiate between chemical species.

Results obtained during examination of the multilayer Co/Au film by different methods of Magnetic Force Microscopy (MFM) are presented. It was shown, that double-pass scanning with MFM tips, characterised by strong magnetic moments resulted in a magnetisation reversal of the sample during MFM imaging. Single pass scanning or use of the MFM tips with low magnetic moments was required to minimise this process. Experimental results demonstrated good correlation between MFM results acquired during single-pass scanning and double-pass scanning with MFM tips characterised by low magnetic moment.

The remagnetization process and the distribution of magnetic moments in arrays of trilayer nanodisks Co(10 nm)/Pd(0.8 nm)/Co(10 nm) with diameters D = 200 and 400 nm were studied by the magnetooptical Kerr effect (MOKE) and magnetic force microscopy (MFM). It is shown that in the nanodisks with D = 200 nm the magnetisation reversal process can be carried out by the vortex states or one-domain configurations with the antiparallel orientation of moments in the adjacent ferromagnetic layers. In arrays of nanodisks with D = 400 nm the vortex states are formed only.

The computer processing of cobalt nanodots magnetic force microscopy was fulfilled. The solution of reverse task of magnetic force microscopy is obtained for surface nanosystems. Superposition of fields, which are generated by a system of magnetic moments in the selected point in space, causes a linear dependence of the force gradient of the dipole-dipole interaction between the components of the vectors.
