A research team, conducted by Assistant Professor Keisuke Tomiyasu of the Graduate School of Science, Tohoku University, has succeeded in observing "spin molecules" emerging in a geometrically frustrated magnet with the use of state-of-the-art inelastic neutron scattering method. A spin molecule refers to spin motions/excitations confined in a geometrical figure less than 1 nanometer. Based on the team's past research papers, the latest work was published in the American physics journal Physical Review Letters on February 15, 2013 (EST). The paper is entitled "Emergence of Highly Degenerate Excited States in the Frustrated Magnet MgCr2O4."
