Critical fluctuations in the spin-orbit Mott insulator Sr $_{3}$ Ir $_{2}$ O $_{7}$

J. G. Vale, S. Boseggia, H. C. Walker +5

X-ray magnetic critical scattering measurements and specific heat measurements were performed on the perovskite iridate Sr $_{3}$ Ir $_{2}$ O $_{7}$ . We find that the magnetic interactions cl…

Persistence of antiferromagnetic order upon La substitution in the $4 d^{4}$ Mott insulator Ca $_{2}$ RuO $_{4}$

D. Pincini, S. Boseggia, R. Perry +11

The chemical and magnetic structures of the series of compounds Ca $_{2 - x}$ La $_{x}$ RuO $_{4}$ [ $x = 0$ , $0.05 (1)$ , $0.07 (1)$ , $0.12 (1)$ ] have been investigated using neutron diffraction…

Band filling control of the Dzyaloshinskii-Moriya interaction in weakly ferromagnetic insulators

G. Beutier, S. P. Collins, O. V. Dimitrova +8

We observe and explain theoretically a dramatic evolution of the Dzyaloshinskii-Moriya interaction in the series of isostructural weak ferromagnets, MnCO $_{3}$ , FeBO $_{3}$ , CoCO $_{3}$ an…
