Hidden spin-order-induced room-temperature ferroelectricity in a peculiar conical magnetic structure

A novel mechanism of spin-induced ferroelectricity is unraveled in the alternating longitudinal conical (ALC) magnetic structure. Because the noncollinear ALC structure possesses a c-axis component with collinear ↑–↑–↓–↓ spin order, spin-driven ferroelectricity along the c axis due to the exchange s...
