Exploration of the topological quantum materials with electron correlation is at frontier physics, as strong interaction may give rise to new phases and transitions. Here we report that a family kagome magnets $R{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ manifest transport properties analogical those in quantum-limit Chern magnet ${\mathrm{TbMn}}_{6}{\mathrm{Sn}}_{6}$.

Abstract While phonon anharmonicity affects lattice thermal conductivity intrinsically and is difficult to be modified, controllable defects routinely function only by scattering phonons extrinsically.

Magnetic frustrated materials are of great interest for their novel spin-dependent transport properties. We report an anisotropic anomalous Hall effect in the triangular itinerant ferromagnet ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$. When current flows along $ab$ plane, ${\mathrm{Fe}}_{3}{\mathrm{GeTe}}_{2}$ exhibits conventional below Curie temperature ${T}_{c}$, which can be depicted by Karplus--Luttinger theory. On other hand, topological shows up ${T}_{c}$ with $c$ axis. The enhancement...

CrGeTe3 recently emerges as a new two-dimensional (2D) ferromagnetic semiconductor that is promising for spintronic device applications. Unlike CrSiTe3 whose magnetism can be understood using the 2D-Ising model, exhibits smaller van der Waals gap and larger cleavage energy, which could lead to transition of magnetic mechanism from 2D 3D. To confirm this speculation, we investigate critical behavior around second-order paramagnetic-ferromagnetic phase transition. We obtain exponents estimated...
