Research Abstract

Various magnetic properties in quantum spin systems depend on strongly their dimensions. Magnetic order in three, two, and one dimensional spin systems have been studied extensively. Magnetic order in zero dimensional spin systems consisting of a few spins (spin cluster systems) have not been understood well. We studied magnetism of Cu2CdB2O6 and elucidated the origin of magnetic order in the spin cluster system consisting of even number spins. We also studied magnetism of SrMn3P4O14 and elucidated the origin of the unique magnetic order in the spin cluster system consisting of odd number spins.
