RuCl3 is discussed as one of the closest realizations of a J=1/2 Kitaev system on a hexagonal lattice. Yet it shows antiferromagnetic (AF) ordering at low temperature signaling the presence of important interactions in addition to the anisotropic Kitaev interactions. AF order can be suppressed by an external magnetic field. The phase diagram and the behavior in high fields are vividly discussed. Here, we probe the magnetic excitation spectrum of RuCl3 with Raman spectroscopy in high magnetic fields. The observed high field excitation spectra yield a detailed insight into the nature of the high field phase.
