A. Bellati et al., MAGNETORESISTANCE OF IMPLANTED POLYPARAPH ENYLENE FILMS IN THE LOW-TEMPERATURE RANGE, Journal de chimie physique et de physico-chimie biologique, 95(6), 1998, pp. 1449-1452
The magnetoresistance of implanted polyparaphenylene films (E= 30 keV,
10(15) ions/cm(2) < D < 5x10(16) ions/cm(2)) is negative in the low t
emperature range, whereas its sign is positive for higher temperature
when the fluence is sufficiently low; the negative component is attrib
uted to localized states which appear during implantation with high fl
uence.
