TL;DR: In this article, the authors reported neutron scattering measurements that reveal broad spin excitations covering a wide region of the Brillouin zone in an extremely clean antiferromagnet YbMgGaO4.

TL;DR: Inelastic neutron scattering measurements were performed to study spin dynamics in the non-centrosymmetric antiferromagnet α-Cu 2 V 2 O O 7, where the breaking of spatial inversion and time reversal symmetry was revealed as a magnetic-field-induced asymmetric energy shift as discussed by the authors.

TL;DR: In this article, the ground state of trilayer nickelates is shown to be magnetic and the magnetic ordering occurring in individual trilayers that are essentially uncorrelated along the crystallographic $c$ axis.

TL;DR: In this article, the authors used neutron diffraction to study the structure and magnetic phase diagram of the newly discovered pressure-induced superconductor CrAs and showed that CrAs exhibits a spin reorientation from the $ab$ plane to the $ac$ plane, along with an abrupt drop of the magnetic propagation vector at a critical pressure.

TL;DR: In this article, inelastic neutron scattering was used to study spin waves in the antiferromagnetic ordered phase of iron pnictide NaFeAs throughout the Brillouin zone.
