Abstract
  • In this work we analyse systematically how morphological and magnetotransport properties of manganite thin films are affected by the damage induced by focused ion beam ( FIB) irradiation. We irradiate different areas of the same sample with doses ranging from 5 x 10 12 to 3 x 10(17) ions/cm(2) and we find that the film becomes swollen for doses up to 10(16) ions/cm(2) and is eventually eroded by ion milling for further irradiation. On the other hand, transport properties are much more sensitive to FIB irradiation: the metal - insulator transition temperature is found to decrease monotonically with increasing doses up to 1.8 x 10(13) ions/cm(2). At doses higher than 5.6 x 10(13) ions/cm(2) the metallic state is completely suppressed and likely, also ferromagnetism. (C) 2008 Elsevier B. V. All rights reserved. (literal)
