Both characters of the bending of the inverse susceptibility as a function of temperature and the 1/3 plateau of magnetization found in the Monte Carlo simulation study for the triangle based lattice systems survive even in a single triangle cluster. The quantum effect and the spin magnitude are discussed concerning the characters.}, pages = {41--49}, title = {Magnetic susceptibility and magnetization plateau in triangular spin cluster}, volume = {57}, year = {2007}, yomi = {イソダ, マコト} }
