High quality c-axis oriented YBaCuO films, epitaxially grown on (100)
SrTiO3 substrates, were photolithographically patterned to allow Hall
measurements at different temperatures 4K less than or equal to T less
than or equal to 300K in magnetic fields up to B less than or equal t
o 5 T aligned parallel to the surface normal. In this way, the tempera
ture and field dependence of the longitudinal rho(xx)(B,T) and transve
rse resistivity rho(xy)(B,T)] were determined before and after irradia
tion with 350 keV He+ ions. The resulting changes of the temperature d
ependence of the longitudinal resistivity, Hall resistivity and invers
e Hall angle are reported.
