Electric field driven magnetic phase transition in graphene nanoflakes

Aiping Zhou, Weidong Sheng, and S. J. Xu

Within the framework of Hubbard model, a bowtie-shaped graphene nanoflake is identified to undergo an electric-field induced phase transition from an antiferromagnetic ground state. Unlike the case of half-metallic graphene nanoribbons, the electric field here leads to a non-magnetic state instead ... [Appl. Phys. Lett. 103, 133103 (2013)] published Mon Sep 23, 2013.
