| contents | Incorporating zero-net-magnetization magnets that exhibit spin-splitting into spintronics delivers key advantages: faster switching dynamics, greater immunity to destabilizing fields, lower power consumption, and markedly improved overall efficiency. The collinear magnets with net-zero magnetization and spin-splitting mainly include altermagnet and fully-compensated ferrimagnet, which provide possibility to achieve hidden spin polarization (HSP) with net-zero spin polarization in total but non-zero local spin polarization. In addition to proposal of hidden altermagnetism, we hereby introduce this concept of hidden fully-compensated ferrimagnetism, where the total spin polarization is zero, but either of the two inversion-partner sectors possesses fully-compensated ferrimagnetism with non-zero local spin polarization in the real space. By the first-principle calculations, we predict that $PT$-bilayer $\mathrm{CrMoC_2S_6}$ is a possible hidden fully-compensated ferrimagnet, showing fully-compensated ferrimagnetic HSP, which can be separated and observed by an out-of-plane external electric field. Our works provide a class of hidden spin-polarized materials that facilitates the advancement of spintronics. |
