  We have optimized the growth of superconducting TaN thin films on \ch{SiO2}
substrates via dc magnetron sputtering and extract a maximum superconducting
transition temperature of $T_{\mathrm{c}}=5$ K as well as a maximum critical
field $\mu_0H_{\mathrm{c2}}=(13.8\pm0.1)$ T. To investigate the impact of
spin-orbit interaction in superconductor/ferromagnet heterostructures, we then
analyze the magnetization dynamics of both normal state and superconducting
TaN/\ch{Ni80Fe20}(Permalloy, Py)-bilayers as a function of temperature using
broadband ferromagnetic resonance (bbFMR) spectroscopy. The phase sensitive
detection of the microwave transmission signal is used to quantitatively
extract the inverse current-induced torques of the bilayers. The results are
compared to our previous study on NbN/Py-bilayers. In the normal state of TaN,
we detect a positive damping-like current-induced torque $\sigma_{\mathrm{d}}$
from the inverse spin Hall effect (iSHE) and a small field-like torque
$\sigma_{\mathrm{f}}$ attributed to the inverse Rashba-Edelstein effect (iREE)
at the TaN/Py-interface. In the superconducting state of TaN, we detect a
negative $\sigma_{\mathrm{d}}$ attributed to the quasiparticle mediated inverse
spin Hall effect (QMiSHE) and the unexpected manifestation of a large positive
field-like $\sigma_{\mathrm{f}}$ of unknown origin matching our previous
results for NbN/Py-bilayers.
