Evidence for magnetic Weyl fermions in a correlated metal.
Experimental evidence is reported for magnetic Weyl fermions in Mn3Sn, a non-collinear antiferromagnet that exhibits a large anomalous Hall effect, even at room temperature, and lays the foundation for a new field of science and technology involving the magnetic Wey excitations of strongly correlated electron systems such as Mn3 Sn.

Giant anomalous Nernst effect and quantum-critical scaling in a ferromagnetic semimetal
In conducting ferromagnets, an anomalous Nernst effect—the generation of an electric voltage perpendicular to both the magnetization and an applied temperature gradient—can be driven by theExpand
Spin-Orbital Short-Range Order on a Honeycomb-Based Lattice
Ba3CuSb2O9, which is magnetically anisotropic at the atomic scale but curiously isotropic on mesoscopic length and time scales, is found to have a broad spectrum of spin-dimer–like excitations and low-energy spin degrees of freedom that retain overall hexagonal symmetry. Expand
Successive phase transitions and phase diagrams for the quasi-two-dimensional easy-axis triangular antiferromagnet Rb4Mn(MoO4)3
Using magnetic, thermal and neutron measurements we show that Rb4Mn(MoO4)3 is a quasi-2D triangular Heisenberg antiferromagnet with easy-axis anisotropy and successive transitions bracketing anExpand
Low-dimensional structure and magnetism of the quantum antiferromagnet Rb4Cu(MoO4)3 and the structure of Rb4Zn(MoO4)3.
Low-temperature thermodynamic measurements have revealed that a quantum paramagnetic state with Wilson ratio approximately 2 remains stable down to at least 0.1 K, 100 times lower than the intrachain antiferromagnetic coupling scale. Expand
High-Resolution Synchrotron Studies and Magnetic Properties of Frustrated Antiferromagnets MAl2S4 (M = Mn2+, Fe2+, Co2+)
Single crystals of MAl2S4 (M = Mn2+, Fe2+, Co2+) were synthesized using the chemical vapor transport method and characterized using high-resolution synchrotron X-ray diffraction to determine theExpand
Structure and magnetism of the quasi-1-d K4Cu(MoO4)3 and the structure of K4Zn(MoO4)3.
Comparison of the structure and magnetic properties of isostructural A(4)Cu(MoO(4))(3) (A = K, Rb) allows the isolation of the effects of low dimensionality from structural distortion along the Cu-O-Mo chains. Expand
Successive phase transitions and phase diagrams of $S$ = 5/2 quasi-two dimensional triangular antiferromagnet Rb$_{4}$Mn(MoO$_{4})_{3}$
Submitted for the MAR10 Meeting of The American Physical Society Successive phase transitions and phase diagrams of S = 5/2 quasi-two dimensional triangular antiferromagnet Rb4Mn(MoO4)3 RIEKO ISHII,Expand
Magnetotransport properties in the noncentrosymmetric itinerant ferromagnet Cr 11 Ge 19
We have investigated anomalous Hall effect and magnetoresistance in a noncentrosymmetric itinerant magnet Cr$_{11}$Ge$_{19}$. While the temperature- and magnetic-field-dependent anomalous HallExpand
