Abstract : We have (1) developed high-resolution magnetic force microscopy (including a new MFM tip structure and calibration ring) and used it to investigate patterned magnetic structures; (2) found that the in-plan magnetoresistance of nanoscale squares is over 600 % due to the well-defined magnetic domain structures induced by the small size and shape anisotropy; and (3) observed spin-valve effects in ferromagnetic/semiconductor/ferromagnetic diodes.
