Quasi two dimensional magnetic structure of the triclinic double perovskite Ca $_{2}$ CuWO $_{6}$

Bangye Qin, Dmitry D. Khalyavin, Xuan Liang +3

We present the antiferromagnetic ground state of the triclinic double perovskite Ca $_{2}$ CuWO $_{6}$ solved by neutron powder diffraction, and analyze it in direct comparison with tetrag…

Competing collinear and non-collinear spin textures imaged by spatially-resolved REXS in Eu(Al0.4Ga0.6)4

Fellipe B. Carneiro, Zéetény Bacsó, Kevin Allen +6

Here, we use resonant elastic x-ray scattering (REXS) to investigate the inhomogeneity of the zero-field magnetic spin texture of Eu(Al $_{0.4}$ Ga $_{0.6}$ ) $_{4}$ . By using spatially-r…

Inverse Melting of 3D Antiferromagnetic Order in Multi-sublattice Magnetic Perovskites

Bangye Qin, Dmitry D. Khalyavin, Ran Liu +3

In conventional antiferromagnets a long-range ordered 3D ground state transitions to a disordered paramagnetic state on warming, often via lower dimensional spin correlations withi…

Modification of Charge and Spin Textures by Light Chemical Substitution in Eu(Al $_{1 - x}$ Ga $_{x}$ ) $_{4}$ ( $x = 0.1$ )

Zétény Bacsó, Fellipe Carneiro, Kevin Allen +6

We present the results of a resonant X-ray diffraction experiment, resolving both charge and spin textures in the intermetallic topological magnet Eu(Al $_{1 - x}$ Ga $_{x}$ ) $_{4}$ , $x$ =…

The magnetic structures of rare-earth quadruple perovskite manganites $R$ Mn $_{7}$ O $_{12}$

R. D. Johnson, D. D. Khalyavin, P. Manuel +3

We report a neutron powder diffraction study of $R$ Mn $_{7}$ O $_{12}$ quadruple perovskite manganites with $R$ = La, Ce, Nd, Sm, and Eu. We show that in all measured compounds concomit…
