We consider stably rotating highly magnetised neutron stars and glitching
pulsars. We discuss the prospects for detecting continuous gravitational waves
from these sources below 20 Hz with next-generation ground-based facilities
such as the Einstein Telescope and Cosmic Explorer and space-based
observatories such as DECIGO and Big Bang Observer. We demonstrate that these
constitute interesting science targets. We use a robust sensitivity estimation
method for future searches based on demonstrated performance. We show that the
spin-down upper limit on the gravitational wave amplitude of more than 90% of
all highly magnetised pulsars and magnetars suitable for a years-long fully
coherent search, exceeds the smallest gravitational wave amplitude estimated
detectable with DECIGO and Big Bang Observer. We find that the hidden magnetar
candidate PSR J1852+0040 can be detected by Cosmic Explorer if it is emitting
at least at 20% of its spin-down luminosity. Finally, post-glitch transient
continuous gravitational waves from magnetars are an interesting target for
deci-Hz detectors, with all but one of the recorded glitches giving rise to a
spin-down limit signal above the smallest detectable level.
