Erratum: Direct observation of composite fermions and their fully-spin-polarized Fermi sea near ν=5 /2 (Physical Review Letters (2018) 120 (256601) DOI: 10.1103/PhysRevLett.120.256601)

In the third paragraph of our Letter we implied that the inelastic light scattering experiments presented in [1] suggest that the v=5/2 fractional quantum Hall state is spin unpolarized. This implication is not accurate. In experiments of [1], spin wave modes observed at v= 5 / 2 at the bare Zeeman energy indicate a high degree of spin polarization. The results and conclusions presented in our Letter remain unaffected. ACKNOWLEDGEMENTS We thank Aron Pinczuk and Ursula Wurstbauer for pointing out the mistake.
