  The Parkes Multibeam Survey led to the identification of a number of
long-period radio pulsars with magnetic field well above the 'quantum critical
field' of ~ 4.4x10^13 G (HBRPs). The HBRPs have similar spin parameters to
magnetars, but their emission properties are different, and contradict those
theories that predict that radio emission should be suppressed above this
critical field. Our observations support the suggestion that initial neutron
star spin periods depend on their magnetic fields; in particular, there is a
tendency for high-field systems to be born as slow rotators. The aim of this
project is to understand the emission properties of HBRPs, using multiple radio
frequencies and high time resolution data. One specific objective is to
identify HBRPs radio emission characteristics that are different from those of
normal pulsars.
