What is it about?
RTFM is believed to originate surface defects. Is this really a surface phenomenon? We have investigated this question using a metal-insulator transition material and finally, RTFM was concluded to a surface phenomenon.

Why is it important?
Existence of ferromagnetism in both insulation and metallic regions reveals that RTFM is a surface phenomenon. And, the surface to the volume ration was estimated by the amount of magnetization variation at the transition temperature in case of VO2 nanoparticles.
