FIG. 1.

(a) Magnetic hysteresis loop of FeMnC alloy tip from the MOKE measurements and the switching field smaller than can be characterized. (b) Magnified image of soft magnetic tip taken by the SEM.

FIG. 2.

(a) Topographic image of 0.35 ML bilayer high Co nanoislands grown on Cu(111) (image size , , and ). (b) and (c) are the spin-polarized conductance mapping images recorded at −316 mV and −494 mV, respectively. (d) Top: spin-polarized conductance curves recorded from two set of Co nanoislands with same stackings and nearly same sizes as indicated from A to D in the inset of (b) and (c). Bottom: structural and magnetic asymmetry curves.

Image of FIG. 3.
FIG. 3.

(a) Spin polarized conductance mapping image of 0.66 ML bilayer high Co nanoislands and the black spots on the surface of Co nanoislands are segragated Cu atoms. The corresponding topography is shown in the inset. (b) Reversed spin contrast image taken after the magnetization switching of front tip end. (c) Similar spin contrast image to the (a) taken after tip magnetization reverse again. (d) Tunneling spectra of a set of two Co nanoislands taken before and after magnetization switchings of tip end. (image sizes are all , taken at and ).
