We introduce a scheme to coherently suppress second-rank tensor frequencyshifts in atomic clocks, relying on the continuous rotation of an externalmagnetic field during the free atomic state evolution in a Ramsey sequence. Themethod retrieves the unperturbed frequency within a single interrogation cycleand is readily applicable to various atomic clock systems. For the frequencyshift due to the electric quadrupole interaction, we experimentally demonstratesuppression by more than two orders of magnitude for the ${}^2S_{1/2} \to{}^2D_{3/2}$ transition of a single trapped ${}^{171}\text{Yb}^+$ ion. Thescheme provides particular advantages in the case of the ${}^{171}\text{Yb}^+$${}^2S_{1/2} \to {}^2F_{7/2}$ electric octupole (E3) transition. For animproved estimate of the residual quadrupole shift for this transition, wemeasure the excited state electric quadrupole moments $\Theta({}^2D_{3/2}) =1.95(1)~ea_0^2$ and $\Theta({}^2F_{7/2}) = -0.0297(5)~ea_0^2$ with $e$ theelementary charge and $a_0$ the Bohr radius, improving the measurementuncertainties by one order of magnitude.
