Bismuth ferrite (BiFeO3) is one of the most widely studied multiferroics. The coexistence of
ferroelectricity and antiferromagnetism in this compound has driven an intense search for …

Multiferroic materials have attracted much interest due to the unusual coexistence of
ferroelectric and (anti-) ferromagnetic ground states in a single compound. They offer an …

To face the challenges lying beyond present technologies based on complementary metal–
oxide–semiconductors, new paradigms for information processing are required. Magnonics …

We unravel the magnon spectra of BiFeO 3 by means of low-energy inelastic light scattering.
We show the existence of two species of magnons corresponding to spin wave excitations in …

Temperature-dependent Raman spectroscopic studies of spin-phonon (SP) coupling and
magnon scattering in bulk and few-layer (FL) antiferromagnet (AFM) FePS 3 with Néel …

The magnetic-field-dependent spin ordering of strained BiFeO3 films is determined using
nuclear resonant scattering and Raman spectroscopy. The critical field required to destroy …

The article provides a tutorial review on how to treat Ising models within mean-field (MF),
effective-field (EF) and exact methods. MF solutions of the spin-1 Blume-Capel (BC) model …

We have determined the full magnetic dispersion relations of multiferroic BiFeO 3. In
particular, two excitation gaps originating from magnetic anisotropies have been clearly …

We report neutron diffraction and magnetization studies of the magnetic order in multiferroic
BiFeO 3. In ferroelectric monodomain single crystals, there are three magnetic cycloidal …

Antiferromagnets host exotic quasiparticles, support high frequency excitations and are key
enablers of the prospective spintronic and spin–orbitronic technologies. Here, we propose a …
