We propose a method for nano-scale characterization of long range magnetic order in diluted magnetic systems to clarify the origins of the room temperature ferromagnetism. The GaN:Mn thin films are gr...
Metal-Insulator Transition and Magnetic Order in the Pyrochlore Oxide Hg2Ru2O7

2010/11/17
We report results of NMR experiments on the ruthenium oxide Hg2Ru2O7 with the py-rochlore structure, which exhibits a metal-insulator transition at TMI = 107 K. In the metallic
phase above TMI, the n...
