A detailed magnetoresistance study of bulk and microflake samples of highlyoriented pyrolytic graphite with a thickness of 25 $\mu$m to 23~nm reveals thatthe usually observed field-induced metal-insulator and electronic phasetransitions vanish in thinner samples. The observed suppression is accompaniedby orders of magnitude decrease of the magnetoresistance and of the amplitudeof the Shubnikov-de-Haas oscillations. The overall behavior is related to thedecrease in the quantity of two-dimensional interfaces between crystallineregions of the same and different stacking orders present in graphite samples.Our results indicate that these field-induced transitions are not intrinsic tothe ideal graphite structure and, therefore, a relevant portion of thepublished interpretations should be reconsidered.
