NICER observed several rotation-powered millisecond pulsars to search for orconfirm the presence of X-ray pulsations. When broad and sine-like, thesepulsations may indicate thermal emission from hot polar caps at the magneticpoles on the neutron star surface. We report confident detections($\ge4.7\sigma$ after background filtering) of X-ray pulsations for five of theseven pulsars in our target sample: PSR J0614-3329, PSR J0636+5129, PSRJ0751+1807, PSR J1012+5307, and PSR J2241-5236, while PSR J1552+5437 and PSRJ1744-1134 remain undetected. Of those, only PSR J0751+1807 and PSR J1012+5307had pulsations previously detected at the 1.7$\sigma$ and almost 3$\sigma$confidence levels, respectively, in XMM-Newton data. All detected sourcesexhibit broad sine-like pulses, which are indicative of surface thermalradiation. As such, these MSPs are promising targets for future X-rayobservations aimed at constraining the neutron star mass-radius relation andthe dense matter equation of state using detailed pulse profile modeling.Furthermore, we find that three of the detected millisecond pulsars exhibit asignificant phase offset between their X-ray and radio pulses.
