The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different...

We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, LaFePO and Sr2ScFePO3. The objective is to...

The relationship between spin fluctuations and superconductivity is an important issue in condensed matter physics. Part of evidence suggesting direct correlation between spin...

In the last few years functionalised carbon nanotubes and carbon nanofibers have shown promising results in the area of heterogeneous catalysis due to the ability to tune the...

We have devoted much efforts to investigating the doping evolution of the magnetic excitations in electron doped BaFe2-xNixAs2 (x=0-0.6). Spin excitations for x=0-0.6 have been...

Understanding the magnetism in iron pnictides is one of the most important steps to reveal the mechanism of superconductivity in these novel materials. In the extensively...

ACo2As2 (A=Ba, Sr, Ca) are end members of Co doped Ba-122 family. Understanding the magnetic behavior of these end members can help us to understand the magnetic properties of...

the correlation degree in 122 iron pnictides mainly depends on the electronoccupancy of each orbital and that by doping electrons the correlation decreases monotonically. This...

We propose to measure spin waves in detwinned SrFe2As2, combined with our data on detwinned BaFe2As2 this allows us to understand if magnetic excitations in the two systems can...
