The magnetic nature of the spinel antiferromagnet Li[Lix Mn2-xO4 with x = 00.15 has been studied with muon-spin-rotation and relaxation (μ+SR) spectroscopy. Both weak transverse field and zero field μ+ SR measurements indicate that the whole sample enters into a static disordered magnetic phase below TN for all the samples measured; TN = 61 K for LiMn2O4, whereas 27=23 K for the x = 0.050.15 samples. It was also clarified that both the field distribution width and the field fluctuation rate show a clear change at the Jahn-Teller transition temperature (T JT = 280 K) for LiMn2O4, and a short-range cooperative JT distortion appears below 280 K even for Li[Li0.15Mn1.85]O4.
