A neutron diffraction image showing the scattering results from a barium-iron-arsenide sample that includes sodium ions attached to 24% of the barium sites. 2nd order symmetry exists below a temperature of 90K but 4th order symmetry returns at a temperature below 40K. The resulting atomic and magnetic structures are shown on the right side of the figure, where the blue circles represent iron atoms, and the red arrows represent the direction of their magnetic momentum.

Part of the array of the superconducting nanoloops. The diameter of the wires in the picture is 25 nanometers. The length of the wires in the small loops is 150 nanometers and in the large ones 500 nanometers, while the diameter of the wires that make up each loop is 25 nanometers (photo: the laboratory of Prof. Yosef Yeshuron, Bar-Ilan University)
