We report on the measurement of lifetimes and magnetic moments of yrast states in ${}_{}{}^{134}{}_{}{}^{}\mathrm{Nd}$ and ${}_{}{}^{136}{}_{}{}^{}\mathrm{Nd}$. Lifetimes in the 10–100 ps range were measured via the recoil distance Doppler shift method applied to the reactions ${}_{}{}^{110}{}_{}{}^{}\mathrm{Pd}$${(}^{28}$,30Si,4n) at 120–125 MeV beam energy. Magnetic moments of the $2_1^{+}$ state in ${}_{}{}^{134}{}_{}{}^{}\mathrm{Nd}$ and the ${10}^{+}$ and ${12}^{+}$ yrast states in ${}_{}{}^{136}{}_{}{}^{}\mathrm{Nd}$ were deduced from the integral Larmor precessions measured after recoil implantation in a magnetized nickel foil, via the reactions ${}_{}{}^{76}{}_{}{}^{}\mathrm{Ge}$${(}^{62}$,64Ni,4n). The ${10}^{+}$ backbending state in ${}_{}{}^{136}{}_{}{}^{}\mathrm{Nd}$ results from $h_{11/2}$ proton (two quasiparticle) alignment. The paramagnetic relaxation time of Nd in nickel was measured by Coulomb excitation and implantation of ${}_{}{}^{148}{}_{}{}^{}\mathrm{Nd}$($2_1^{+}$).
