Lifetimes of states of a magnetic dipole band in each of the nuclei, {sup 106,108}Sn have been obtained using the Doppler Shift Attenuation Method. The deduced B(M1) transition rates show the characteristic behavior associated with the shears mechanism. A simplified semi-classical analysis yields B(M1) values in qualitative agreement with those expected for previously assigned configurations. The results suggest extremely low deformations for these dipole structures. The {sup 106}Sn band appears to be the first example of almost pure magnetic rotation in a spherical nucleus.
