We report on the observation of a mixed-spin-channel Feshbach resonance at the low magnetic field value of 9.09\ifmmode±\else\textpm\fi0.01\phantom\rule0.3em0exG for a mixture of \ensuremath|2,\ensuremath-1⟩ and \ensuremath|1,+1⟩ states in 87Rb. This mixture is important for applications of multicomponent Bose-Einstein condensates of 87Rb, e.g., in spin mixture physics and for quantum entanglement. Values for position, height, and width of the resonance are reported and compared to a recent theoretical calculation of this resonance.
