Unique magnetism in a graphene ladder-type Ising system under an applied transverse field

The phase diagrams and magnetization curves of a graphene ladder-type Ising system under an applied transverse field are investigated by using the effective-field theory with correlations. They have exhibited many characteristic phenomena, such as the reentrant phenomena exhibiting the three transition temperatures. In particular, the thermal variations of transverse magnetizations have exhibited some characteristic features not found in other...
