Two-dimensional (2D) ferroics, namely ferroelectric, ferromagnetic, and ferroelastic
materials, are attracting rising interest due to their fascinating physical properties and …

Kagome magnet has been found to be a fertile ground for the search of exotic quantum
states in condensed matter. Arising from the unusual geometry, the quantum interactions in …

The efficiency of spintronic devices can be improved by generating higher effective magnetic
fields with lower working currents. Spin-transfer torques can drive magnetic domain wall …

Understanding and manipulating emergent phases, which are themes at the forefront of
quantum-materials research, rely on identifying their underlying symmetries. This general …

Broken symmetries and electronic topology are well manifested together in the second-order
nonlinear optical responses from topologically non-trivial materials. Although second-order …

We study the low-energy single-electron transport across a junction of two magnetic Weyl
semimetals, in which the anisotropy axes are tilted one respect to the other. Using a two …

Exchange bias is a phenomenon critical to solid-state technologies that require spin valves
or nonvolatile magnetic memory. The phenomenon is usually studied in the context of …

We predict a novel metallic state of matter that emerges in a Weyl-semimetal superstructure
with spatially varying Weyl-node positions. In the new state, the Weyl nodes are stretched …

Microscopic understanding of magnetization switching via domain nucleation and/or domain-
wall propagation is fundamental knowledge for developing magnetic and spintronic devices …

Exploring the relationship between intriguing physical properties and structural complexity is
a central topic in studying modern functional materials. Co3Sn2S2, a newly discovered …
