Discovery of d-orbital order in Tb2CoAl4Ge2
Zhanyang Hao, Haohao Sheng, Wanru Ma +32
Orbital order describes a quantum state where occupied orbitals line up in a periodic pattern. While orbital physics plays a fundamental and universal role in strongly correlated e…
Odd spin symmetry and anisotropy switching in p-wave magnet CeNiAsO
Fayuan Zhang, Huaxun Li, Xingkai Cheng +18
Odd-parity magnets, complementary to altermagnets, exhibit unique properties such as high efficiency in charge-spin conversion and compatibility with conventional superconductivity…
Orthorhombic nitride perovskite CeTaN3-δ with switchable and robust ferroelectric polarization
Guozhu Song, Xiangliang Zheng, Xiaodong Yao +16
Perovskite-type ternary nitrides with predicted exciting ferroelectricity and many other outstanding properties hold great promise to be an emerging class of advanced ferroelectric…
Bose-Einstein condensation of a two-magnon bound state in a spin-one triangular lattice
Jieming Sheng, Jia-Wei Mei, Le Wang +31
In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired in…
