Title: Physical properties of V 1-xTixO₂ (0 < x < 0.187) single crystals

Free standing, low strain, single crystals of pure and titanium doped VO₂ were grown out of an excess of V ₂O₅ using high temperature solution growth techniques. At TMI ~ 340 K, pure VO₂ exhibits a clear first-order phase transition from a high-temperature paramagnetic tetragonal phase (R) to a low-temperature non-magnetic monoclinic phase (M1). With Ti doping, another monoclinic phase (M2) emerges between the R and M1 phases. The phase transition temperature between R and M2 increases with increasing Ti doping while the transition temperature between M2 and M1 decreases.
