We consider a spinor condensate of 87Rb atoms in its F=1 hyperfine state atfinite temperatures. Putting initially all atoms in m_F=0 component we findthat the system evolves into the state of thermal equilibrium. This state isapproached in a step-like process and when established it manifests itself indistinguishable ways. The atoms in states m_F=+1 and m_F=-1 start to rotate inopposite directions breaking the chiral symmetry and showing highly regularspin textures. Also the coherence properties of the system changesdramatically. Depending on the strength of spin-changing collisions the systemfirst enters the stage where the m_F=+1 and m_F=-1 spinor condensate componentsperiodically loose and recover their mutual coherence whereas their thermalcounterparts get completely dephased. For stronger spin changing collisions thesystem enters the regime where also the strong coherence between othercomponents is built up.Comment: 5 pages, 4 figure
