Subpicosecond lifetimes of states near the bandhead of an M1 band in {sup 198}Pb have been measured with the recoil-distance Doppler-shift technique using the Gammasphere array and the Cologne plunger. The deduced B(M1) values are in agreement with the predictions of the tilted axis cranking (TAC) model. Their spin dependence continues the trend set by recently published B(M1) values for the high spin states in this band. The emerging picture gives strong support to the concept of {open_quotes}magnetic rotation,{close_quotes} an alternative mode for the generation of rotational spectra in nuclei. {copyright} {ital 1998} {ital The American Physical Society}
