We study the Abelian flux tube profile of mesonic and the baryonicconfigurations of static quarks below and above the finite-temperaturetransition in $N_f=2$ full QCD. To reduce effects of ultra-violet fluctuationswe measure Abelian distributions of the action density, the color-electricfield and the monopole current after fixing to the maximally Abelian gauge.Changing the distance $R$ between quarks for fixed $T/T_c<1$, one can see aclear signal of string breaking for large $R$. The electric field becomesCoulomb-like and the circulating monopole current disappears. We study also thetemperature dependence of the flux profile for fixed $R \approx 0.7$ fm. Thedisappearance of the squeezed flux is observed clearly above $T_c$. Similarbehaviors are observed both in the mesonic and the baryonic systems.Comment: 17 pages, 13 figures, Late
