Effects of the magneto-crystalline anisotropy on the magnetic properties of Fe/Cr/Fe (110) trilayer
In this paper we present a theoretical study about the influence of the magneto-crystalline anisotropy on the magnetic properties of magnetic metallic trilayers Fe/Cr/Fe (110). The theory is based on a realist...

The N-membranes Problem with Neumann Type Boundary Condition
We consider the problem of finding the equilibrium position of N membranes constrained not to pass through each other, under prescribed volumic forces and boundary tensions. This model corresponds to solve variat...

Spin-wave Theory for the Magnetic Dam** in Microwave Nano-Oscillators
Here we present a calculation for the linewidth of the spin-wave that is generated when a spin valve nanostructure is traversed by a high-density spin-polarized direct current. In this case, the magnetization ...

Open AccessInfluence of substrate type and magnetic anisotropy on the spin Seebeck effect in ZnFe2O4 thin films
The longitudinal spin Seebeck effect (LSSE) has been investigated in ZnFe2O4 (ZFO) thin films on different substrates, such as Si (111), MgO (100), and SrTiO3 (100). The LSSE voltage signal exhibited a linear dep...
