关联p波磁体候选材料CeNiAsO的有序磁矩异常微小，这对精确测定其磁结构构成了严重挑战，阻碍了对其基本性质的理解。利用对局域内场的高灵敏度，我们的⁷⁵As核四极/磁共振实验揭示了一种 commensurate 反铁磁序，其面外磁矩m_z≈0.05 μ_B。这种倾斜磁构型不仅使自旋极化轴偏离晶体学c轴，还增强了非相对论自旋分裂，我们将这种罕见范式称为“倾斜p波磁体”。
英文摘要
The unexpectedly small ordered moments of CeNiAsO, a candidate for correlated $p$-wave magnet, have posed a serious challenge to the precise determination of its magnetic structure, hindering the understanding of its fundamental properties. By leveraging the high sensitivity to local internal fields, our $^{75}$As nuclear quadrupole / magnetic resonance experiments reveal a commensurate antiferromagnetic order with a small out-of-plane moment $m_z\approx0.05$ $μ_{\mathrm{B}}$. This tilted magnetic configuration not only rotates the spin polarization axis away from the crystallographic $\mathbf{c}$-axis, but also enhances the non-relativistic spin splitting. We refer to this rare paradigm as a \textit{tilted $p$-wave magnet}.
