Hydrostatic pressure to trigger and assist magnetic transitions: Baromagnetic refrigeration
(American Institute of Physics, 2014-01)
The possible application of the barocaloric effect to produce solid state refrigerators is a topic of interest in the field of applied physics. In this work, we present experimental data about the influence of external ...
The Liquid Water−Benzene System
(Universidad de Belgrano - Facultad de Ciencias Exactas y Naturales - Proyectos de Investigación, 2006)
The 500 MHz NMR spectra of water−benzene solution near saturation at 303.15, 323.15, and 343.15 K indicate that there is a proton−proton exchange between the water and benzene molecules. In the solution water appears to ...

Structural phase transition study of FePt alloys using ab initio calculation
(Elsevier B.V. Sa, 2009-09-25)
The FePt alloy undergoes the cubic to tetragonal lattice transformation in the ferromagnetic state. We calculated the electronic structure for both cubic and tetragonal structures using the FPLAPW method with APW + lo. ...

Insight into the Effects of Fe Addition on the Local Structure and Electronic Properties of SrTiO3
(Amer Chemical Soc, 2014-03-06)
This paper reports an experimental and theoretical investigation of the effects of adding Fe to the perovskite strontium titanate SrTiO3. The effects include changes in the short-order range structure as well as in the ...
Effect of phonons on the optical properties of color centers in diamond
(2017)
During the last decade color centers in large band gap materials have received great attention due to the large degree of control that is possible to achieve of their internal degrees of freedom. They are leading candidates ...
Relaxation and tunnelling of structural units within the LTO phase of La2CuO4
(Editrice Compositori Bologna, 1998-07-01)
The anelastic relaxation (elastic energy loss and Young modulus) of nearly stoichiometric La2CuO4+delta with LTO structure was measured. Extraordinarily intense effects are present below room temperature in the elastic ...
In situ solid state oxidation reaction for La1-xSrxMnO3 (x=0, 0.1, 0.2 and 0.3) formation
(Elsevier B.V., 2001-05-01)
In situ solid state oxidation reaction for an alternative La1-xSrxMnO3 (x = 0, 0.1, 0.2 and 0.3) formation is reported. Samples have been obtained by using strontium peroxide, lanthanum and manganese (III) oxide reagents. ...
Spectroscopic investigation of a new hybrid glass formed by the interaction between croconate ion and calcium polyphosphate
(Elsevier B.V., 2005-07-01)
In this work, a new organic-inorganic hybrid material has been synthesized by the incorporation of croconate ion into a calcium polyphosphate coacervate. The hybrid so obtained was characterized by means of electronic and ...
