▎ 摘　　要

Understanding the magnetic phase transition induced by strain has attracted considerable interest due to the indispensability of strain in practical condensed matter system. In this letter, we adopt meanfield approximation to study the effect of strain on magnetism and magnetic phase transition in slightly doped graphene nanoribbons of sublattice number N = 20 and N = 25. It is found that only in the case of strain level A > 0.4 along zigzag direction, the magnetic phase transition associated with alternating ferromagnetic correlated two edges (FMCE) state and antiferromagnetic correlated two edges (AFCE) state can occur ascribed to the unique zigzag-edged magnetic states generated from the quantum interference. These findings provide the possibility to promote application in strain based spintronic devices. (c) 2021 Elsevier B.V. All rights reserved.
