Abstract

The magnetic nature of the spinel antiferromagnet Li[Li_x Mn_2-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 T_N for all the samples measured; T_N = 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[Li_0.15Mn_1.85]O₄.
