Coupling Chirality, Polar Order, and Altermagnetic Spin Splitting in a Hybrid Manganese Chloride
Li Liang, Ding Ning, Mingqiang Gu +2
Hybrid manganese halides enable the coexistence of molecular chirality, polar order, and magnetic exchange within a single lattice. Here, we combine first-principles calculations w…
Excitations across the equilibrium and photoinduced `hidden' states of magnetoresistive manganites
Shiyu Fan, Feng Jin, Taehun Kim +16
"Hidden" phases, generated using ultrafast laser pulses (few hundred femtoseconds), with properties distinct from thermodynamic equilibrium, are appealing for technologies because…
Magnetic order dependent photoluminescence from high energy excitons in hBN protected few-layer CrSBr
Xiaohua Wu, Junyang Chen, Mingqiang Gu +6
The detection and manipulation of the spin configurations in layered magnetic semiconductors hold significant interest for developing spintronic devices in two-dimensional limit. I…
Sliding ferroelectric control of unconventional magnetism in stacked bilayers
Yongqian Zhu, Mingqiang Gu, Yuntian Liu +4
The control of unconventional magnetism, which displays ferromagnetism-like properties with compensated magnetization, has drawn intense attention for advancing antiferromagnetic s…
Ferroelectric switchable altermagnetism
Mingqiang Gu, Yuntian Liu, Haiyuan Zhu +5
We propose a novel ferroelectric switchable altermagnetism effect, the reversal of ferroelectric polarization is coupled to the switching of altermagnetic spin splitting. We demons…
