Unusual ferroelectric and magnetic phases in multiferroic 2H-BaMnO ceramics
Stanislav Kamba, Dmitry Nuzhnyy, Maxim Savinov +16
The structural phase transition in hexagonal BaMnO occurring at =130 K was studied in ceramic samples using electron and X-ray diffraction, second harmonic generation as w…
Magnetoelectric Effects in the Spiral Magnets CuCl and CuBr
P. Tolédano, A. P. Ayala, A. F. G. Furtado Filho +3
The nature and symmetry of the transition mechanisms in the spin-spiral copper halides CuCl and CuBr are analyzed theoretically. The magnetoelectric effects observed in the…
Multiferroicity and magnetoelectric coupling in α-CaCr2O4
Kiran Singh, Charles Simon, Pierre Toledano
Ferroelectricity in the incommensurate helical magnetic phase (below TN, 43K) of alpha CaCr2O4 has been confirmed by pyroelectric measurements. Magnetoelectric and magnetodielectri…
Coupling of replicate order-parameters in incommensurate multiferroics
Bruno Mettout, Pierre Toledano
The specific properties of incommensurate multiferroic phases resulting from the coupling of order-parameter replicates are worked out using the illustrative example of iron vanada…
Unconventional Multiferroicity in Cupric Oxide
Pierre Toledano, Naemi Leo, Dmitry D. Khalyavin +4
The magnetic phase transitions reported below 230 K in cupric oxide are analyzed theoretically at the macroscopic and microscopic levels. The incommensurate multiferroic and lock-i…
Spontaneous toroidic effects in Ba2CoGe2O7
Pierre Toledano, Dmitry D. Khalyavin, Laurent C. Chapon
The unusual magnetoelectric effects observed in the multiferroic phase arising below TN=6.7K in Ba2CoGe2O7 (BCG) are related to the spontaneous toroidal moment existing in this com…
