Abstract Many complex magnetic structures in a high-symmetry lattice can arise from a superposition of well-defined magnetic wave vectors. These “multi-q” structures have garnered much attention because of interesting real-space spin textures suc

Layered trigonal ${\mathrm{EuMg}}_{2}{\mathrm{Bi}}_{2}$ is reported to be a topological semimetal that hosts multiple Dirac points that may be gapped or split by the onset of magnetic order. Here, we report zero-field single-crystal neutron-diffracti

Neutron diffraction and magnetic susceptibility studies show that orthorhombic single-crystals of topological semimetals $\mathrm{Sr}({\mathrm{Mn}}_{0.9}{\mathrm{Cu}}_{0.1}){\mathrm{Sb}}_{2}$ and $\mathrm{Sr}({\mathrm{Mn}}_{0.9}{\mathrm{Zn}}_{0.1}){\

Magnetic Weyl semimetals are expected to have extraordinary physical properties such as a chiral anomaly and large anomalous Hall effects that may be useful for future, potential, spintronics applications. However, in most known host materials, multi

${\mathrm{SrCo}}_{2}{\mathrm{As}}_{2}$ is a peculiar itinerant magnetic system that does not order magnetically, but inelastic neutron-scattering experiments observe the same stripe-type antiferromagnetic (AF) fluctuations found in many of the Fe-bas

Neutron diffraction and magnetic susceptibility studies of orthorhombic single crystal $({\mathrm{Sr}}_{0.97}{\mathrm{K}}_{0.03}){\mathrm{MnSb}}_{2}$ confirm the three-dimensional (3D) C-type antiferromagnetic (AFM) ordering of the ${\mathrm{Mn}}^{2+

Whereas magnetic frustration is typically associated with local-moment magnets in special geometric arrangements, here we show that SrCo$_{2}$As$_{2}$ is a candidate for frustrated itinerant magnetism. Using inelastic neutron scattering (INS), we fin

We report on the crystal and magnetic structures, magnetic, and transport properties of SrMnSb$_2$ single crystals grown by the self-flux method. Magnetic susceptibility measurements reveal an antiferromagnetic (AFM) transition at $T_{\rm N} = 295(3)

The magnetic order in CaK(Fe[1-x]Ni[x])4As4 (1144) single crystals (x = 0.051 and 0.033) has been studied by neutron diffraction. We observe magnetic Bragg peaks associated to the same propagation vectors as found for the collinear stripe antiferroma

The microscopic details of the suppression of antiferromagnetic order in the Kondo-lattice series Ce$_{1-x}$La$_{x}$Cu$_{2}$Ge$_{2}$ due to nonmagnetic dilution by La are revealed through neutron diffraction results for $x=0.20$, $0.40$, $0.75$, and
