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...

Open AccessVocal universals and geographic variations in the acoustic repertoire of the common bottlenose dolphin
Acoustical geographic variation is common in widely distributed species and it is already described for several taxa, at various scales. In cetaceans, intraspecific variation in acoustic repertoires has been l...

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 ...

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...
