Resonances of coherent population trapping were detected in atomic vapours of the rare-earth element samarium. The coherent population trapping was produced by two external-cavity diode lasers (672 and 686 nm) in a {Lambda}-system formed by the three levels of {sup 154}Sm: the 4f{sup 6}6s{sup 2}({sup 7}F{sub 0}) ground state, the first fine-structure 4f{sup 6}6s{sup 2}({sup 7}F{sub 1}) sublevel of the ground state and the 4f{sup 6}({sup 7}F)6s6p({sup 3}P{sup o}){sup 9}F{sup o}{sub 1} upper level. The dependence of the spectral shapes and resonance contrasts on the polarisation of the laser beams and the direction of the applied magnetic field was studied. The obtained results were analysed.
