“…Therefore, it would be extremely interesting to experimentally investigate α-iron crystals at negative pressures and low temperatures to detect unusual elastic properties of these crystals. In this connection the new method of measuring the speed of sound proposed in [38] might be very helpful. It measures the speed of sound both in the compression area and at crystal tension.…”

Based on the detailed ab initio calculations of electronic structure for hcp-zinc and bcc-ferromagnetic iron, we made an attempt to study a scale of anomalies emerging in the calculations of elastic properties of these crystals as functions of pressure, and determine a relation between these anomalies and electronic topological transitions. Our calculations give grounds to believe that an electronic topological transition in itself is not a cause of significant anomalies in elastic properties of crystals but is, probably, an indicator of rearrangement of the crystal energy spectrum: an indicator which is not even always present. In some cases such rearrangement can cause significant anomalies in elastic and other properties of the crystal.
