Visualizing ferroic domains in an all-in–all-out antiferromagnet thin film

Antiferromagnetic domain distribution is analyzed by a scanning superconducting quantum interference device microscopy for a pyrochlore \mathrm{T}{\mathrm{b}}_{2}\mathrm{I}{\mathrm{r}}_{2}{\mathrm{O}}_{7}thin film with an all-in--all-out (AIAO) spin arrangement. The local magnetic field on the surface is found to originate predominantly from the \mathrm{T}{\mathrm{b}}^{3+}(J=6)magnetic moment. While \mathrm{I}{\mathrm{r}}^{4+}magnetic...
