摘要	It is demonstrated that spin splitting can be induced and further modulated in a one-dimensional (1D) helical melem chain with a helical structure by first-principles calculations. The spin splitting occurs at the charge-localized states at valence band due to the breaking of inversion symmetry by the helical structure. The maximum spin-split energy reaches 0.81 meV, without any heavy elements in the melem chain. The helical melem chain is facile to stretch or compress, as a molecule spring with a spring constant of 1.04 N m(-1), leading to the spin-split energy effectively varying from 0.81 (196 GHz) to 0.04 meV (10 GHz) along with the periodic lattice changing from 4.0 to 15.0 angstrom. These results exhibit a unique mechanism for driving the spin splitting in 1D materials, in particular for those helical big molecules, and that in fact offers an original way to not only design the regulatable 1D components in the fields of spintronics but also measure the helix of molecule chains by resonating with microwave frequency.
