3: 1 magnetization plateau and suppression of ferroelectric polarization in an Ising chain multiferroic
Physical Review B—Condensed Matter and Materials Physics, 2009•APS
Ferroelectric Ising chain magnet Ca 3 Co 2− x Mn x O 6 (x≃ 0.96) was studied in magnetic
fields of up to 33 T. Magnetization and neutron-scattering measurements reveal successive
metamagnetic transitions from the zero-field↑↑↓↓ spin configuration to the↑↑↑↓ state
with a broad magnetization plateau, and then to the↑↑↑↑ state. The absence of
hysteresis in these plateaus reveals an intriguing coupling between the intrachain state and
the three-dimensional geometrically frustrated magnetic system. Inversion symmetry, broken …

Ferroelectric Ising chain magnet was studied in magnetic fields of up to 33 T. Magnetization and neutron-scattering measurements reveal successive metamagnetic transitions from the zero-field spin configuration to the state with a broad magnetization plateau, and then to the state. The absence of hysteresis in these plateaus reveals an intriguing coupling between the intrachain state and the three-dimensional geometrically frustrated magnetic system. Inversion symmetry, broken in the state, is restored in the state, leading to the complete suppression of the electric polarization driven by symmetric superexchange.
