LiTi₂O₄ and related spinel compounds have attracted considerable attention both as a superconductor as well as an electrode material for Li-ion batteries. In this brief report we have studied thin (220 nm) films of LiTi₂O₄ using the low-energy muon spin rotation/relaxation (LEM) technique. By performing temperature dependent measurement using the vortex state protocol in moderate magnetic fields it is possible to follow the entrance into the superconducting state below T_c = 12 K. Further, the London penetration depth at T = 5 K and 100 G applied field is extracted as λ_ab≈ 226 nm.
