Abstract
Steps, which in some points of the (110)planes become spiral pits, were obtained on the surface of silicon iron by electrolytic etching. The height of the steps, which was from tens to 1000 Å,was measured by multiple beam interference. An explanation of the step-like etching is proposed and some of the mechanisms, which can lead to the production of etch spirals with the above height of the steps, are given.
