Electron holography of one cobalt nanosphere with a diameter of 110 nm. a) Electron hologram of the object. b) Electrostatic phase image, φE. c) Colored representation of the in-plane magnetic induction flux lines, represented as cos(12·φM). The inset represents the color scale of the magnetic induction orientation in arbitrary units, where the position of a color relative to the center of the circle corresponds to the orientation of the magnetic induction. d) Profile of the in-plane component of the magnetic induction vector as measured along the white arrow c), where the position reference is taken at the minimum of the magnetic induction.
