A search for resonant absorption of solar axions by 169Tm nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on Tm3Al5O12 crystal was used that allowed for significant improvement of sensitivity in comparison with previous 169Tm based experiments. Themeasurements performed with 8.18 g crystal during 6.6 days exposure yielded the following limits on axion couplings: |gAγ (g0 AN + g3 AN) ≤ 1.44×10−14 GeV−1 and |gAe(g0 AN +g3 AN) ≤ 2.81×10−16.
