Polarization observations of nine southern millisecond pulsars

Abstract

Mean pulse profiles and polarization properties are presented for nine southern pulsars. The observations were made using the Parkes radio telescope at frequencies near 1330 MHz; three of the nine pulsars were also observed at 660 MHz. A very high degree of circular polarization was observed in PSR J1603-7202. Complex position angle variations which are not well described by the rotating-vector model were observed in PSRs J2124-3358 and J2145-0750, both of which have very wide profiles. Rotation measures were obtained for all nine pulsars, with two implying relatively strong interstellar magnetic fields.
