A nanoscale structure analysis method using convergent-beam electron diffraction (CBED) has been applied to an orbital-ordered state of Fe 2+ 3d electrons in a spinel oxide FeCr2 O4. The atom positions, atomic displacement parameters, electrostatic potential, and electron density have been determined using CBED intensity data alone. A ferro-type ordered state of the 3 z2 - r2 orbitals at the tetrahedrally coordinated Fe atoms has been successfully observed through the electrostatic potential obtained in the present analysis.
