The macroscopic quantum coherence in a biaxial antiferromagnetic molecular magnet in the presence of magnetic field acting parallel to its hard anisotropy axis
A great improvement on a previous work (Phys. Rev. B48 (1993) 14067) has been made. By taking intoaccount all the irreducible representations and their componen
In dealing with the square lattice model,we replace the traditionally needed Born-Von Karmann periodic boundary condition with additional Hamiltonian terms to m
We investigate the effect of the position of the donor in quantum dots on the energy spectrum in the presence ofa perpendicular magnetic field by using the meth
