New triangular lattice layered compound MnSnTeO6 with unique chiral
crystal structure was prepared and its static and dynamic magnetic
properties were studied both experimentally (through magnetization, specific
heat, neutron diffraction and ESR) and theoretically (through ab initio DFT
calculations). Magnetic susceptibility and specific heat evidence an onset of
antiferromagnetic order at TN~10 K. However, there observes an additional
first order transition at T*~5 K, which can’t be related to structural one as
confirmed from the neutron data. The ground state was found to be stabilized
by seven exchange parameters determined via ab initio DFT calculations.
All of them are significant, but there is a remarkable difference triggered by
chiral structure: the left-handed interactions are weaker than the right-handed
ones. The spin dynamics was (ESR data) discussed in the terms of critical
broadening and BKT scenario.
Elena Zvereva has completed her PhD in 2000 and
habilitation in 2017 from Lomonosov Moscow State
University, Russia. She is Professor Associate of Phys-
ics Faculty of Lomonosov Moscow State University,
Russia. She has over 100 publications that have been
cited over 300 times. Scientific interests include wide
class of quantum cooperative phenomena in Con-
densed Matter Physics, with emphasis on strongly
correlated electron system, low dimensional magne-
tism, novel functional materials for Li-ion batteries
fabrication and spintronics. Research activities are
related to the fundamental characterization of static,
dynamic and resonant physical properties of the new
complex oxides and chalcogenides of transition, alkali
and rare-earth metals.
