In the present study the course of spin transformation in the linear trinuclear [Fe3(bntrz)6(tcnset)6] complex, exhibiting a complete one step transition at T=318K, and in the tetranuclear protonated [Fe4(H6L4)]6+ and ...

A crystal containing a Co(II) ion in the octahedral cubic surrounding as a structural element is examined. The total Hamiltonian of the crystal includes the crystal field acting on the Co(II) ion, the spin-orbital interaction ...
