The tidal force from a third body near a binary system could introduce
long-term oscillations in the binary’s eccentricity, known as Kozai-Lidov
oscillations. We show that the Kozai-Lidov oscillations of stellar-mass black
hole binaries have the potential to be observed by LISA. Detections of such
binaries will give insights into binary formation channels and also provide an
important benchmark of observing Kozai-Lidov oscillations directly.
