Valuation of magnetic non-collinear effects on FM/trans-PA/FM systems

With Greenʹs function method and single band tight binding Hamiltonian, we calculated coherence transport for trans-polyacetylene (T-PA) systems placed between ferromagnetic electrodes with non-collinear ones. Ferromagnetic electrodes are of two kinds: Fe and Ni. With increasing TMR angle it increases to a maximum at θ=π degree. Electric field on molecule causes a change in the value of TMR. Types of ferromagnetic electrodes also affect the value of TMR, which is caused by density of states related to electrodes.
