| Resumo | |
Themagnetic structure of Ca2MnReO6 double perovskite is investigated by neutron powder diffraction and bulk magnetization, showing dominant noncollinear Mn magnetic moments [4.35(7) mu(B)] that are orthogonally aligned with the small Re moments [0.22(4) mu(B)]. Ab initio electronic structure calculations show that the strong spin-orbit coupling for Re 5d electrons combined with a relatively modest on-site Coulomb repulsion (U-eff(Re) greater than or similar to 0.6 eV) is sufficient to render this material insulating. This is a rare example of spin-orbit-assisted Mott insulator outside the realm of iridates, with remarkable magnetic properties. (AU) | |
