Structural, magnetic and magnetocaloric properties in distorted RE ₂NiTiO₆ double perovskite compounds

Magnetic properties and magnetocaloric effect of NdMn2-xCuxSi2 compounds

Structural and magnetic properties of NdMn2−x Cu xSi2 compounds (x = 0-1.0) have been investigated by high intensity x-ray and resolution neutron diffraction (3-450 K), specific heat, dc magnetization, and differential scanning calorimetry measurements. Substitution of Cu for Mn leads to an increase in the lattice parameter a but a decrease in c at room temperature. Two magnetic phase transitio...

The new ternary silicide Gd5CoSi2: Structural, magnetic and magnetocaloric properties

EXPERIMENTAL AND THEORETICAL STUDY OF THE STRUCTURAL, MAGNETIC AND ELECTRONIC PROPERTIES OF THE BA2GDSBO6 PEROVSKITE

In this work the procedure to the synthesis of Ba2GdSbO6 complex perovskite by the solid-state reaction method is reported. Theoretically a study of the crystalline and electronic structure was performed into the framework of the Density Functional Theory (DFT). The most stable structure is obtained to be a rhombohedral perovskite with a lattice constant a=6,0840 Å.  Due the occurren...

Excellent magnetocaloric properties in RE2Cu2Cd (RE = Dy and Tm) compounds and its composite materials

The magnetic properties and magnetocaloric effect (MCE) of ternary intermetallic RE2Cu2Cd (RE = Dy and Tm) compounds and its composite materials have been investigated in detail. Both compounds undergo a paramagnetic to ferromagnetic transition at its own Curie temperatures of TC ~ 48.5 and 15 K for Dy2Cu2Cd and Tm2Cu2Cd, respectively, giving rise to the large reversible MCE. An additionally ma...

Structural, magnetic and electrical properties of a new double-perovskite LaNaMnMoO6 material

Structural, magnetic, magnetocaloric, electrical and magnetoresistance properties of an LaNaMnMoO6 powder sample have been investigated by X-ray diffraction (XRD), magnetic and electrical measurements. Our sample has been synthesized using the ceramic method. Rietveld refinements of the XRD patterns show that our sample is single phase and it crystallizes in the orthorhombic structure with Pnma...
