  Materials with significant spin-orbit coupling enable efficient
spin-to-charge interconversion, which can be utilized in novel spin electronic
devices. A number of elements, mainly heavy-metals (HM) have been identified to
produce a sizable spin current ($j_\mathrm{s}$), while supplied with a charge
current ($j$), detected mainly in the neighbouring ferromagnetic (FM) layer.
Apart from the spin Hall angle $\theta_\mathrm{SH}$ = $j_\mathrm{s}$/$j$, spin
Hall conductivity ($\sigma_\mathrm{SH}$) is an important parameter, which takes
also the resistivity of the material into account. In this work, we present a
measurement protocol of the HM/FM bilayers, which enables for a precise
$\sigma_\mathrm{SH}$ determination. Static transport measurements, including
resistivity and magnetization measurements are accompanied by the angular
harmonic Hall voltage analysis in a dedicated low-noise rotating probe station.
Dynamic characterization includes effective magnetization and magnetization
damping measurement, which enable HM/FM interface absorption calculation. We
validate the measurement protocol in Pt and Pt-Ti underlayers in contact with
FeCoB and present the $\sigma_\mathrm{SH}$ of up to 3.3$\times$10$^5$ S/m,
which exceeds the values typically measured in other HM, such as W or Ta.
