“…The mean distance between the magnetoexcitons in the bound state is 0 , Rl where 0 l is the magnetic length. The calculations with more cumbersome wave function corresponding to the bound state with resulting spin 0 S  formed by 4 two ortho-magnetoexcitons confirmed the earlier obtained results [14,15] and allow to better understand the uniqueness of the triplet-triplet spin configuration studied earlier and its importance in similar biexciton spin structures in the absence of the magnetic field.…”

“…The metastable bound state with a lifetime of about few picoseconds, and possibility of a new luminescence band due to the radiative recombination of one electron-hole pair and the conversion of the metastable bound state into the para-magnetoexciton and the emission the photon was predicted in [14,15]. The new luminescence band should be at the higher energy side compared to the paramagnetoexciton luminescence line.…”

Four different spin structures of two electrons and of two holes situated on the lowest Landau levels (LLLs) are taken into account to investigate possible bound states of the two-dimensional magnetic biexciton formed of two magnetoexcitons with opposite wave vectors and antiparallel dipole moments. The singlet and triplet states of the spins of two electrons and of two holes separately, as well as of two para-and two ortho-magnetoexcitons are considered. The general expressions describing the binding energy of the bound states and the normalization conditions characterized by the parameter 1, 1 2     for the corresponding wave functions are derived. It is shown that for all four spin configurations the stable bound states in the LLLs approximation do not exist. The most favorable of the four considered spin configurations happened to be the triplet-triplet spin structure of two electrons and of two holes. In its frame a metastable bound state with activation barrier comparable with two ionization potentials of the magnetoexciton is revealed.
