Electron paramagnetic resonance measurements revealed a ferromagnetic phase transition taking place near room temperature in quasi-two-dimensional dodecylamine-intercalated vanadium pentoxide with a mixed structure of coexisting lamellar and rectangular phases. It is shown that the ferromagnetism can be ascribed to the rectangular phase, whereas the paramagnetic lamellar phase undergoes no magnetic transition.
