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

The hexagonal RMnO3 (h-RMnO3) are multiferroic materials, which exhibit the coexistence
of a magnetic order and ferroelectricity. Their distinction is in their geometry that both results …

We elucidate the role of magnon interaction and spontaneous decays in the spin dynamics
of the triangular-lattice Heisenberg antiferromagnet by calculating its dynamical structure …

Specific heat measurements and theoretical calculations reveal an intimate analogy
between EuTiO 3 and SrTiO 3. For EuTiO 3, a hitherto unknown specific heat anomaly is …

The hexagonal phase of LuFe O 3 is a rare example of a multiferroic material possessing a
weak ferromagnetic moment, which is predicted to be switchable by an electric field. We …

The nontrivial magnon band topology and its consequent responses have been extensively
studied in two-dimensional magnetisms. However, the triangular lattice antiferromagnet …

The breakdown of magnons, the quasiparticles of magnetic systems, has rarely been seen.
By using an inelastic neutron scattering technique, we report the observation of …

The structural, electric, and magnetic properties of bulk hexagonal LuFe O 3 are
investigated. Single phase hexagonal LuFe O 3 has been successfully stabilized in the bulk …

Magnons and phonons are fundamental quasiparticles in a solid and can be coupled
together to form a hybrid quasi-particle. However, detailed experimental studies on the …

We observe a disappearance of the 1/3 magnetization plateau and a striking change of the
magnetic configuration under a moderate do** of the model triangular antiferromagnet …
