We performed inelastic magnetic neutron scattering experiments on the high-Tc superconductor La2−x−ySrxREyCuO4 with RE=Dy (x=0, 0.25 and y=0.09) and RE=Nd (x=0, 0.12, 0.15, 0.2 and y=0.1, 0.3). In this system an additional low temperature phase t

We observed for the first time a first-order phase transition with strong and extremely anisotropic changes of the lattice parameters in compounds crystallizing in the ThCr2Si2 structure type. The phase transition occurs SrRh2P2 with increasing press

According to x-ray absorption, Mossbauer effect measurements, lattice constants and static susceptibility, Eu in the novel compound is non-integral valent with a valence of the order of 2.2. On the other hand, the compound orders antiferromagneticall

Inelastic magnetic neuron scattering experiments on the high-Te superconductor La2−x−ySrxNdyCuO4 were carried out. We investigated the relaxation behavior of the 4f moments for different Sr and Nd concentrations. In all our samples, the high-temp
