Unique phenomena induced by an exchange interaction between two graphene-like Ising nanoparticles in an applied transverse field
The phase diagrams and the magnetizations of graphene-like nanoparticles which are constructed from two paramagnetic honeycomb units and an inter-unit exchange interaction r are investigated by using the effective-field theory with correlations. They have exhibited some characteristic phenomena, such as the reentrant phenomena, when the value of r is larger than r = 1.0 and a transverse field is applied.
