説明

Neutron scattering measurements of an antiferromagnet spinel LiMn2O4 were performed using a polycrystalline sample. A bump signal peaked at 1.4, Å-1 appears below 100, K, though the line width of the magnetic diffraction pattern remains broad even at 8, K. Additionally, Mn spins freeze below 60, K. In LiMn2O4, magnetic ions, i.e., Mn3+ and Mn4+, form a network of corner-shared-tetrahedra. The observed magnetic pattern is explained by the following charge and the magnetic ordering. Two Mn3+ ions and two Mn4+ ions randomly distribute on four corners of each tetrahedron. The antiferromagnetic correlation exists only in the arrangements of Mn3+--Mn3+ and Mn4+--Mn4+ and no correlation in Mn3+--Mn4+; this is due to the frustration of spins between the arrangements of Mn3+--Mn3+ and Mn4+--Mn4+.
