Figure 3

(a) The effective transverse magnetic field around the half of sensor stripe. The ratio of local magnetic field to the applied field was plotted in log scale. (b) The magnetic field from a nanoparticle at different locations on the surface normalized by the volume of the nanoparticle. The nanoparticle is moved from the center of the sensor stripe to the middle of the trench along the surface. An increase in field at 400 nm is resulted from the changes in height indicated by the red arrow. The positive sign in y axis means the same direction as an applied field.
