The magnetic properties of paramagnetic/weakly ferromagnetic films are strongly affected by the proximity to materials that undergo a metal to insulator phase transition. Here, we show that under the deposition conditions associated with structural changes near the metal-insulator phase transition of VO(sub2) produces magnetoelastic anisotropy. We observe intrinsic paramagnetic centres (PM-C) both at the near film surface and bulk/deep PM-C that are affected by the metal-insulator phase transition in VO2. We study the evolution of vibrational modes of VO(sub2) thin films in the vicinity of the phase transition by using temperature controlled-Raman microscopy.
