A search for resonant absorption of solar axions by 169 Tm nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on Tm 3 Al 5 O 12 crystal was used that allowed for significant improvement of sensitivity in comparison with previous 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 γ ( g AN 0 + g AN 3 ) ≤ 1.44 × 10 - 14 GeV - 1 and | g Ae ( g AN 0 + g AN 3 ) ≤ 2.81 × 10 - 16 .
