Unravelling spin fluctuation components in a stripe-ordered cuprate
In previous experiments at ILL we observed a gap in the magnetic excitation spectrum of the stripe-ordered superconductor (La,Nd)2-xSrxCuO4, x=0.12. We observed a spin gap of... -
Charting the increase in spin fluctuations as we approach the critical point ...
The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,...
