Recent research activities on the linear magnetoelectric (ME) effect—induction of
magnetization by an electric field or of polarization by a magnetic field—are reviewed …

Complex perovskite oxides exhibit a rich spectrum of properties, including magnetism,
ferroelectricity, strongly correlated electron behaviour, superconductivity and …

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 …

Second-harmonic generation (SHG) in magnetically ordered crystals is reviewed. The
symmetry of such crystals is determined by the arrangement of both the charges and 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 …

We have studied the structural phase transition of multiferroic Y Mn O 3 from first principles.
Using group-theoretical analysis and first-principles density functional calculations of the …

The crystal and magnetic structures of single-crystalline hexagonal LuFeO 3 films have been
studied using x-ray, electron, and neutron diffraction methods. The polar structure of these …

We show that the improper ferroelectric phase transition in the multiferroic hexagonal
manganites displays appropriate symmetry-breaking characteristics for testing the Kibble …

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 …
