We reveal the microscopic origin of elec. polarization P→ induced by noncollinear magnetic order. We show that in Mott insulators, such P→ is given by all possible combinations of position operators r→j=(r→ij0,r→ij) and transfer integrals tj=(tij0,tij) in the bonds, where r→ij0 and tij0 are spin-independent contributions in the basis of Kramers doublet states, while r→ij and tij stem solely from the spin-orbit interaction. Among them, the combination tij0r→ij, which couples to the spin current, remains finite in the centrosym. bonds, thus yielding finite P→ in the case of noncollinear arrangement of spins. The form of the magnetoelec. coupling, which is controlled by r→ij, appears to be rich and is not limited to the phenomenol. law P→~εijx[eixej] with εij being the bond vector connecting the spins ei and ej. Using d.-functional theory, we illustrate how the proposed mechanism works in the spiral magnets CuCl2, CuBr2, CuO, and α-Li2IrO3, providing a consistent explanation for the available exptl. data.Cupric bromide(cas: 7789-45-9Related Products of 7789-45-9) was used in this study.
Cupric bromide(cas: 7789-45-9) can be used as reducing agent, when complexed by three molecules of pyridine initiators for the controlled polymerization of styrene, methyl acrylate and methyl methacrylate.Related Products of 7789-45-9
