Instability of a ferrimagnetic state of a frustrated =1/2 Heisenberg antiferromagnet in two dimensions

Nakano, Hiroki*; Sakai, Toru

To clarify the instability of the ferrimagnetism which is the fundamental magnetism of ferrite, numerical diagonalization study for the two-dimensional =1/2 Heisenberg antiferromagnet with frustration. We find that the ferrimagnetic ground state has the spontaneous magnetization in small frustration.
