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…
