Abstract
The surface of iron meteorite consisting of FeNi–FeS has been studied with scanning tunneling microscope. Fairly good topographic maps for a large area (−3 μm) are obtained showing strong ridge structures with 200–700 nm in spacing, 100–400 nm in valley depth. The top of the ridges has also been observed in more detail. Structures like parallel ridges, promontorylike with faceted surfaces can be seen clearly, which possess some characters as in process of crystallite growth pattern on the earth.
