Multiferroics are those materials with more than one ferroic order, and magnetoelectricity
refers to the mutual coupling between magnetism (spins and/or magnetic field) and …

Hexagonal manganites belong to an exciting class of materials exhibiting strong interactions
between a highly frustrated magnetic system, the ferroelectric polarization, and the lattice …

Hexagonal YMnO3 shows a unique improper ferroelectricity induced by structural
trimerization. Extensive research on this system is primarily due to its candidacy for …

AMPLIMODES is a computer program available on the Bilbao Crystallographic Server that
can perform a symmetry-mode analysis of any distorted structure of displacive type. The …

The description of displacive distorted structures in terms of symmetry-adapted modes is
reviewed. A specific parameterization of the symmetry-mode decomposition of these …

Since their discovery in 1963 the hexagonal manganites have consolidated their role as
exotic ferroelectrics with astonishing functionalities. Their introduction as room-temperature …

We report a detailed high-resolution powder neutron diffraction investigation of the structural
behavior of the multiferroic hexagonal polymorph of YMnO 3 between room temperature and …

We discovered stripe patterns of trimerization-ferroelectric domains in hexagonal REMnO 3
(RE= Ho,⋯, Lu) crystals (grown below ferroelectric transition temperatures (T c), reaching up …

Recent studies demonstrated the violation of reciprocity in optical processes in low-
symmetry magnetic crystals. In these crystals the speed of light can be different for …

The improper ferroelectricity in YMnO 3 and other related multiferroic hexagonal manganites
is known to cause topologically protected ferroelectric domains that give rise to rich and …
