Abstract
Li1+x(Ni1/2Mn1/2)1-xO2 was prepared by co-precipitation and calcination technique. The compounds had a layered rock-salt structure with R3m symmetry, and the degree of non-stoichiometry x was an important factor for the structural and magnetic properties. The degree of cationic ordering was improved with an increase in x and simultaneously, the ferrimagnetic characters were reduced. That is, the magnetic interaction network is converted from three-dimensional to two-dimensional ones, and is restricted within each c-plane. Hence, the long range magnetic correlation as well as the local magnetic interaction is weakened. The spontaneous magnetization was evaluated using a ferrimagnetic cluster model. As the degree of non-stoichiometry was increased, the cluster density was reduced, and it resulted in the lowering in the spontaneous magnetization at low temperature.
