Recent observations at high radio frequencies using the Effelsberg 100-m Radio Telescope of the Max-Planck-Institut für Radioastronomie have resulted in the detection of four millisecond pulsars at 4.85 GHz ; PSRs J1022+1001, J1713+0747, B1855+09 and J2145-0750. The typical flux density for these millisecond pulsars is around 1 mJy. Pulse shapes and flux densities of observed millisecond pulsars are presented.

Key words: Pulsars: general – millisecond pulsars: individual: J1022+1001, J1713+0747, B1855+09, J2145-0750 – Radiation mechanisms: miscellaneous
