“…[1][2][3][4] In our previous studies, the combination of Pd with magnetic transition metals provided an opportunity to modulate the magnetism, because Pd is an efficient catalyst in the dissociation of hydrogen molecules and the presence of Pd atoms can also help to stabilize hydrogen bounding to transition metals. [5][6][7][8][9][10][11][12] The palladium-hydrogen system has attracted intensive research efforts in physical chemistry as a model system because of its high storage capacity, its high sensitivity and selectivity to H 2 gas, and its ability to easily release hydrogen at room temperature.…”

“…Taking into account this fact, we can extend the Valenta model to the discussion concerning the angular distribution of magnetization in terms of the variational procedure derived in the discrete space. We obtain then not only two orientations of homogeneous distribution but also their inhomogeneous distribution among the sublattices [32]. At the end, it is worth while to notice that the thermodynamic approach to the description of nano-structures within the Valenta model gives the information about the temperature dependence of divers order parameters describing the inhomogeneous system as well as allows to distinguish the properties of any particular homogeneous subsystem which can be defined on the basis of Néel concept of sublattices.…”

The ferromagnetic nano-structures are recently of great interest for modern investigations. A comparison of the experimental data and theoretical results shows that the use of the standard molecular field approximation is insufficient for the description of nano-structure properties. Therefore, we use the effective field approach in order to show the usefulness of the Valenta model generalized in this way. The agreement between experiment and theory is then excellent.The magnetization profiles and the calculated Curie temperatures are presented for the systems consisting of Ni and Co layers with different configuration of the surfaces and interfaces including terraces and wires. We have shown that the position in the system as well as the kind of neighbouring layers and their mutual interactions can determine the shape of magnetization profiles.The use of the Valenta model allows us to present all dependences in the layer resolved mode.

“…In the present paper we will develop a description of SRT from our previous work [7] by introducing the possibility of simultaneous magnetization rotation in two planes: parallel and perpendicular to the surface plane. The spin reorientation phenomena will then be analyzed using a Heisenberg model in thin film geometry with the exchange interaction anisotropy, shape anisotropy and uniaxial anisotropy terms.…”
