Local Spin Induced Magnetism In The Monolayer Nanographene

Abstract

In this paper, we investigated local spin orientation (up or down) effects on magnetizations of the monolayer nanographene by using effective field theory developed by Kaneyoshi. It is found that the monolayer nanographene and its components have very small magnetization (mC1≈mC2≈mC3≈mMLNG≈2.31x10-18≈0) at T≈0.00 for the Jd1<0 (C1-spin up, C2-spin down and C3-spin up). On the other hand, for Jd2<0, Jd3<0, Jd4<0, and Jd5<0, the monolayer nanographene and its components (C1, C2 and C3 atoms) have very large local spin induced magnetization (mC1≈mC2≈mC3≈mMLNG≈1;1>>2.31x10-18) than those of the Jd1<0. These results clearly indicate that the local spin orientation in the monolayer nanographene has very strong effect on its magnetism.
