The extreme softening of spin excitations in electron double layers is studied by resonant inelastic light scattering. At even-integer quantum Hall states we ΓΏnd evidence of three distinct conΓΏgurations of spin. Transformations among these spin states appear as quantum phase transitions tuned by int
