  Magnetoelastic effects in antiferromagnetic CuMnAs are investigated by
applying dynamic strain in the 0.01% range through surface acoustic waves in
the GaAs substrate. The magnetic state of the CuMnAs/GaAs is characterized by a
multitude of submicron-sized domains which we image by x-ray magnetic linear
dichroism combined with photoemission electron microscopy. Within the explored
strain range, CuMnAs shows magnetoelastic effects in the form of N\'eel vector
waves with micrometer wavelength, which corresponds to an averaged overall
spin-axis rotation up to 2.4 deg driven by the time-dependent strain from the
surface acoustic wave. Measurements at different temperatures indicate a
reduction of the wave amplitude when lowering the temperature. However, no
domain wall motion has been detected on the nanosecond timescale
