In this invited lecture I presented a correlation between magnetic amplitude modulation and persistent spin dynamics. This is a rare phenomenon that we have observed in the amplitude modulated magnetic ground state of the FeTe2O5Br system. Based on our experimental results, we also managed to explain the coexistence of long-range magnetic order and persistent spin dynamics, which are generally considered to be mutually exclusive. Moreover, we find that for the observed response Fe-O-Te-O-Fe-exchange paths are vital, as they form a frustrated magnetic network.

COBISS.SI-ID: 27092007In this lecture I also presented the link between the magnetic amplitude modulation and persistent spin dynamics, where I stressed the importance of Fe-O-Te-O-Fe exchange pathways, forming a frustrated magnetic network. The latter is crucial for the realization of complex amplitude-modulated magnetic structure, which coexists with both persistent spin dynamics as well as the electric polarization.
