The texture and magnetic anisotropy of a YBa2Cu3O7-x (YBCO) film growth onto a MgO substrate are analyzed in order to understand the relation between them. X-ray diffraction shows the presence of the (00l) reflections from the YBCO layer with a grain’s fraction value 98%. Rocking Curves (RC) measurements reveal an out-of-plane texture with a full width at the half maximum of 0.81°, revealing a high uniaxial texture in the YBCO film. The temperature dependence of the susceptibility measurements obtained under many applied fields along Hext

In this work, we synthesized and characterized structurally the rare earth iron garnets R3Fe4.9Al0.1O12 (R = Sm, Gd) by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman microscopy, and magnetization. The samples were synthesized using the co-precipitation synthesis method and calcined at a temperature between 500 and 900 °C stepwise 100 °C. Sm3Fe4.9Al0.1O12 and Gd3Fe4.9Al0.1O12 powder samples were indexed with a garnet cubic structure belonging to the Ia3?d space group. Structural analyzes indicate that the inclusion of Al instead of Fe slightly decreases the temperature of magnetic ordering. Crystallite sizes calculated from Scherrer's equation and Williamson-Hall method from XDR were 118 nm and 103 nm for Sm3Fe4.9Al0.1O12 and Gd3Fe4.9Al0.1O12 respectively. The SEM analysis results revealed that the particles were formed with average sizes of 469 nm to Sm3Fe4.9Al0.1O...

In this study, we determined the crystallographic, magnetization and electrical resistivity properties of a EuFe0.5Mn0.5O3 complex perovskite produced using a combustion synthesis method. The sample crystallized as an orthorhombic perovskite belonging to the Pbnm space group. Magnetization measurements indicated spin reorientation at 206 K and weak ferromagnetic-like ordering at low temperatures. Determining the magnetization as a function of the magnetic field demonstrated the presence of magnetic order, even at room temperature. Resistivity measurements indicated the existence of a small polaron conduction mechanism at high temperature. © 2020
