Abstract
We have used LOFAR to perform targeted millisecond pulsar surveys of
Fermi γ-ray sources. Operating at a center frequency of 135 MHz,
the surveys use a novel semi-coherent dedispersion approach where
coherently dedispersed trials at coarsely separated dispersion measures
are incoherently dedispersed at finer steps. Three millisecond pulsars
have been discovered as part of these surveys. We describe the LOFAR
surveys and the properties of the newly discovered pulsars.
