To date, only 69 pulsars have been identified with a detected pulsed radioemission below 100 MHz. A LOFAR-core LBA census and a dedicated campaign withthe Nan\c{c}ay LOFAR station in stand-alone mode were carried out in the years2014$-$2017 in order to extend the known population in this frequency range. Inthis paper, we aim to extend the sample of known radio pulsars at lowfrequencies and to produce a catalogue in the frequency range of 25-80 MHz.This will allow future studies to probe the local Galactic pulsar population,in addition to helping explain their emission mechanism, better characterisingthe low-frequency turnover in their spectra, and obtaining new informationabout the interstellar medium through the study of dispersion, scattering, andscintillation. We observed 102 pulsars that are known to emit radio pulsesbelow 200 MHz and with declination above \SI{-30}{\degree}. We used the the LowBand Antennas (LBA) of the LOw Frequency ARray (LOFAR) international stationFR606 at the Nan\c{c}ay Radio Observatory in stand-alone mode, recording databetween 25-80 MHz. complemented with a few additional candidates. Out of oursample of 102 pulsars, we detected 64. We confirmed the existence of tenpulsars detected below 100 MHz by the LOFAR LBA census for the first time\citep{bilous_lofar_2019} and we added two more pulsars that had never beforebeen detected in this frequency range. We provided average pulse profiles, DMvalues, and mean flux densities (or upper limits in the case ofnon-detections). The comparison with previously published results allows us toidentify a hitherto unknown spectral turnover for five pulsars, confirming theexpectation that spectral turnovers are a widespread phenomenon.
