抄録

Submillimetre and millimetre wave electron spin resonance (ESR) measurements of LiMn2O4 powder samples have been performed using a pulsed magnetic field up to 16T in the temperature region from 4.2 to 265K. Although competition between spin and charge orderings of Mn ions on the octahedral B sites of lithium manganese spinel is expected, geometrical frustration is also expected in LiMn2O4 because the octahedral B sites form the pyrochlore lattice. LiMn2O4 calcined at 600 °C was employed in this study because it turned out to be stoichiometric and have fewer impurities. The detailed temperature dependence of the submillimetre and millimetre wave ESR of this sample will be given and its spin dynamics will be discussed.
