Abstract
A lightly Co-doped spinel Li(Mn0.976Co0.024) 2O4 was prepared which crystallizes into a cubic Fd3̄m structure at 300 K. No structural changes were found as the temperature was reduced to 7 K. Magnetic susceptibility and magnetic neutron diffraction measurements reveal developments of magnetic correlations below 150 K. The magnetic correlations were still short range even at 1.4 K, with a saturated correlation length at ∼100 Å, apparently, Co-doping stabilizing the crystal structure and enhancing the magnetic couplings between the Mn spins.
