I mentioned neutron scattering (or in particular, inelastic neutron scattering) as being one of the most important experimental technique in studying the magnetic properties of matter. This is true if the material has some ordered magnetism. This technique has been used to show the ordered magnetic phase separation in high-Tc superconductors, an observation that some have used to promote the stripes model.

This is a http://arxiv.org/abs/cond-mat/0702024" of what can be known using neutron scattering technique. It pays particular attention to some of the work done on high-Tc cuprates.

Than you ZipperZ, Could you give some suugestion on how
to begin a thoretical research in condensed matter physics?
 
From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
