Query: Diamagnetic d-orbitals Drive Magnetic Structure Selection in the Double
  Perovskite Ba$_2$MnTeO$_6$   B-site ordered A$_2$B'B''O$_6$ double perovskites have a variety of
applications as magnetic materials. Here we show that diamagnetic $d^{10}$ and
$d^0$ B'' cations have a significant effect on the magnetic interactions in
these materials. We present a neutron scattering and theoretical study of the
Mn$^{2+}$ double perovskite Ba$_2$MnTeO$_6$ with a $4d^{10}$ Te$^{6+}$ cation
on the B''-site. It is found to be a Type I antiferromagnet with a dominant
nearest-neighbor $J_1$ interaction. In contrast, the $5d^0$ W$^{6+}$ analogue
Ba$_2$MnWO$_6$ is a Type II antiferromagnet with a significant
next-nearest-neighbor $J_2$ interaction. This is due to a $d^{10}$/$d^0$
effect, where the different orbital hybridization with oxygen 2p results in
different superexchange pathways. We show that $d^{10}$ B'' cations promote
nearest neighbor and $d^0$ cations promote next-nearest-neighbor interactions.
The $d^{10}$/$d^0$ effect could be used to tune magnetic interactions in double
perovskites.
