The giant resonance region from 10 MeV $<{E}_{x}<62$ MeV in $^{56}\mathrm{Fe}$, $^{58}\mathrm{Ni}$, and $^{60}\mathrm{Ni}$ has been studied with inelastic scattering of 240 MeV $\ensuremath{\alpha}$ particles at small angles, including 0\ifmmode^\circ\else\textdegree\fi{}. Most of the expected isoscalar $E0$ and $E2$ strength has been identified below ${E}_{x}=40$ MeV. Between 56 and 72% of the isoscalar $E1$ strength has been located in these nuclei. The mass dependence of the giant monopole energy between $A=40$ and 90 is compared to relativistic and nonrelativistic calculations for interactions with compressibility of nuclear matter ${K}_{\mathrm{NM}}~211--225$ MeV.
