Transfer matrix approach to metal surfaces vibrations
(Elsevier B.V., 1989)
Surface phonons propagating in arbitrary directions in the surface of FCC metals are studied via vibrational Green's functions obtained through the definition of transfer matrices. The dynamical matrix is described in the ...
Finite-size effects on spin configurations in antiferromagnetically coupled multilayers
(American Physical Society, 1992-11-01)
Nonuniform canting states are found for multilayers of a finite size that are constructed from ferromagnetic films which are antiferromagnetically coupled. Our results are applicable to a wide variety of experimentally ...
