Mixed-valent manganese oxides with perovskite structure offer a certain degree of chemical flexibility that allows making systematic studies of the relationship between the electric and magnetic properties with the crystalline structure.Here we present magnetic measurements in La 2/3 (Ca 1-x Sr x ) 1/3 MnO 3 that demonstrate that the adiabatic approximation breaks down at low x, due to the strong coupling of the electronic and the lattice degrees of freedom.

Conventional silver paste for crystalline silicon solar cells exhibits low cell efficiency when deposited by non-contact electrohydrodynamic jet printing because of either high volumetric shrinkage or low packing density when there is no printing pressure applied to the silver paste. Therefore, we develop bimodally dispersed silver paste for electrohydrodynamic jet printing to resolve both volumetric shrinkage and packing density of the conventional silver paste, and its electrical and rheological ...

Heusler type alloys are ferromagnetic and are the ideal material for spin-electronic and magneto-electronic applications due to their interesting magnetic properties. The structural, electronic, elastic and phonon properties of the Ru 2 FeGa Heusler alloy in L21 crystal structure have been analyzed handling density functional theory (DFT) in the Generalized Gradient Approximation (GGA) method. The calculated lattice constant and magnetic moment of Ru 2 FeGa alloy is in good agreement with theoretical ...
