Abstract A search for resonant absorption of solar axions by $$^{169}\mathrm {Tm}$$ 169 Tm nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on $$\mathrm {Tm}_{3} \mathrm {Al}_{5} \mathrm {O}_{12}$$ Tm 3 Al 5 O 12 crystal was used that allowed for significant improvement of sensitivity in comparison with previous $$^{169}\mathrm {Tm}$$ 169 Tm based experiments. The measurements performed with 8.18 g crystal during 6.6 days exposure yielded the following limits on axion couplings: $$|g_{A\gamma } (g_{AN}^0 + g_{AN}^3) \le 1.44 \times 10^{-14}\,{{\mathrm{GeV}}^{-1}}$$ | g A γ ( g AN 0 + g AN 3 ) ≤ 1.44 × 10 - 14 GeV - 1 and $$|g_{Ae} (g_{AN}^0 + g_{AN}^3) \le 2.81 \times 10^{-16}$$ | g Ae ( g AN 0 + g AN 3 ) ≤ 2.81 × 10 - 16 .
