Spin Waves at High Temperature in the Parent Compound of the Superconductor F...
The recently discovered iron based superconductors have transition temperatures second only to the cuprates. The majority of these compounds display superconductivity after... -
High Temperature study of BaFe2As2
Recent unpublished data collected at MAPS by our group revealed that the spin wave dispersion of the Ba(122) parent differ significantly from Ca(122). In Ba(122) there is a... -
Magnetic Excitations of Isolated and Pairs of Co Ions and in MgO
The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions.... -
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... -
Spin excitations in La2O2Fe2OSe2 ¿ A Mott insulator candidate
We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to... -
Spin Excitations and "Hourglass" Dispersion in the Model High-Tc superconduct...
The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to... -
Magnetic excitations in FeCrAs
We propose to carry out inelastic neutron scattering experiments to study magnetic excitation spectrum in FeCrAs. FeCrAs exhibits magnetic ordering around 125 K, which is...
