|Abstract:||The acoustic-electric transformation in high-quality FeSe single crystals is studied. In zero magnetic field we observe an abnormally strong electromagnetic radiation induced by a transverse elastic wave. Usually a radiation of such intensity and polarization is observed only in metals subjected to a high magnetic field (the radiation is caused by the Hall current). We argue that in FeSe in zero magnetic field it is caused by the piezomagnetic effect which is most probably of dynamical origin. We find that the piezomagnetism survives under the transition from the normal to superconducting state. In the superconducting state the electromagnetic signal decreases with decreasing temperature that is connected with the change in the London penetration depth. © Copyright EPLA, 2013.|
