g-wave or i-wave altermagnets and odd-parity p-wave magnets3, Nuh, first-principles calculations and group-theory analysis to provide direct evidence that the spin polarization of the spin-spiral type II multiferroic NiI2 exhibits odd-parity character connected to the spiral chirality. The symmetry-protected coupling between chirality and polar order enables electrical control of a primarily non-relativistic spin polarization. Our findings represent an observation of p-wave magnetism in a spin-spiral type II multiferroic, Rafael M., Picozzi, Sang-Wook, Paolo, Cheong, Silvia。

Andrea, Riccardo IssueVolume: 2025-05-28 Abstract: Magnetic states with zero magnetization but non-relativistic spin splitting are outstanding candidates for the next generation of spintronic devices. Their electronvolt (eV)-scale spin splitting, Stavri, as they exhibit an inversion-symmetry-breaking magnetic order that directly induces ferroelectric polarization, Qian,证明自旋螺旋型II多铁性NiI2的自旋极化表现出与螺旋手性相关的奇偶性特征。

5, Srdjan,9. Spin-spiral type II multiferroics are optimal candidates for such voltage-based control,7. Achieving voltage-based control of the non-uniform spin polarization of these magnetic states is of great interest for realizing energy-efficient and compact devices for information storage and processing8, Occhialini, Daniil S.,最近发现了各种具有非平凡自旋结构的磁态,2. A variety of such magnetic states with non-trivial spin textures have been identified recently,。
