We have studied the effect of substitution of Cr in metastable 1T-CrSe2 by Ti and V on its structural and magnetic properties. The structural transitions observed between 165.180 K in the pure material are stomped by the doping. The pure compound has a magnetization corresponding to an antiferromagnetic (AF) ground state. On Ti substitution, we observe an increase of the lattice constants and a gradual passage towards a ferromagnetic state, while V replacement maintains AF order up to our highest doping, xV = 0.5. With our experimental results and the help of first-principles calculations, we construct the phase diagram of the system.
