Magnetic excitations of layered cuprates studied by RIXS at Cu L3 edge

► We have developed very high resolution RIXS instrumentation. ► Cu L3 RIXS is ideal for studying magnetic excitations in layered cuprates. ► RIXS has been used to map magnon and paramagnon dispersion in HTcS. ► We have developed the first partial polarization analyzer for RIXS in the soft X-rays.
