“…In this paper, we show how to make the artificial energy landscape prevail over the intrinsic random pinning and govern vortex dynamics in YBa 2 Cu 3 O 7-δ (YBCO) thin films, in an unusually wide range of temperatures, and in relatively high magnetic fields. We use a combination of e-beam lithography and ion irradiation to engineer the vortex energy landscape via the modulation of the local electronic properties produced by ion damage 23 . This form of "electronic patterning" allows shaping the vortex energy landscape at the scale of only a few tenths of nanometers.…”

Influence of ion implantation on the magnetic and transport properties of manganite films

“…3 devices using not only manganite films [13][14][15] but also High Tc (HTc) superconductors [16,17]. In this context, understanding the influence of point defects on the physical properties of manganite films has regain importance.…”

“…Ion implantation has been considered a non thermal method that produces lattice disorder by introducing vacancy-interstitial pairs in a controlled way [11,12]. Moreover, ion implantation has gained importance in recent years as a general method to develop nano-scale 3 devices using not only manganite films [13][14][15] but also High Tc (HTc) superconductors [16,17]. In this context, understanding the influence of point defects on the physical properties of manganite films has regain importance.…”
