I synthesized single crystals of TiSe2 intercalated with Cr (III) and Mn (II) in very low concentrations (~ 10 - 0,1 ppm) in order to use these EPR-active ions as sensors in the study of the processes taking place in the electronic subsystem and the lattice during the transition to a state with CDW. Indeed, the EPR spectra of these metals exhibit significant changes at the transition to the CDW state. However, I do not have experience in the interpretation of such spectra, and I can not do it alone. If anyone has expressed interest in participation of this problem, we could do a beautiful work.
