"Lumpy" magnetism (IMAGE) Boston College Caption This image shows a bulk single crystal of Iridium oxide, Sr3Ir2O7, in which researchers introduced Lanthanum as a partial substitute for Strontium (Sr) in order to bring the system close to the antiferromagnetic transition. The team from Boston College and UC Santa Barbara revealed atomic scale visualization of a temperature-driven spatial change of magnetic patterns in a Mott insulator, they reported recently in Science Advances.
