Intrinsic antiferromagnetic half-metal and topological phases from the ferrovalley states of the sliding bilayer altermagnets
Shihao Zhang
Altermagnetism is characterized by non-relativistic spin splitting and zero total magnetic moments. In this work, intrinsic antiferromagnetic half-metallic and topological phases w…
External-field-induced transition from altermagnetic metal to fully-compensated ferrimagnetic metal in monolayer
San-Dong Guo, Qiqi Luo, Shi-Hao Zhang +1
Altermagnets and fully-compensated ferrimagnets are two canonical classes of zero-net-moment magnets. An altermagnetic (AM) half-metal cannot exist due to its AM spin splitting, wh…
Multicolor groups for molecules and solids
Hai-Yang Ma, Shihao Zhang, Hu Xu +2
The local magnetic moments of atoms in a molecule or solid can be designated by different colors. Magnetic groups, or 2-color groups, or black-and-white groups have been applied in…
Sliding-induced ferrovalley polarization and possible antiferromagnetic half-metal in bilayer altermagnets
Xin Zhang, Shihao Zhang
Altermagnets, a newly discovered class of materials, exhibit zero net magnetization while hosting spin-split electronic bands. However, monolayer altermagnets maintain degenerate b…
