Abstract

The acoustoelectric transformation (AET) in the mixed state of FeSe-based superconducting chalcogenides was studied. Dependence of the AET signal on the magnetic field obtained at the initial stages of flux penetration shows a behavior that can be explained only if the piezomagnetism is included in the consideration. This argues that these crystals belong to the class of compounds with broken time-reversal symmetry and are in a state of hidden magnetic order.
