Short range magnetic correlations in Gd3Ga5O12
In recent years topologically complex materials have provoked questions about the basic models of magnetism. These materials have given rise to unusual phenomena, including... -
Anti-ferromagnetic ordering in the super-oxygenated (La,Sr)2CuO4+y supercondu...
We have obtained a LSCOO x = 0.06 single crystal where neutron diffraction shows field induced anti-ferromagnetic order with an onset field in the range 0-1T and increasing... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
Superstructures in high-Tc La(2-x)Sr(x)CuO(4+y)
Previous powder diffraction studies of the superoxygenated La(2-x)Sr(x)CuO(4+y) (LSCO+O) system have not provided a model describing the superstructures of the intercalated... -
Spin orientation in natural nanoscale intergrowths and the origin of giant ex...
The orientation of spins in a natural sample of Ti-bearing hematite (Fe2O3) has been measured previously from 2-300K using neutron powder diffraction. It was shown that spins...
