Project Tittle: Study of Magnetic Properties of Electron-Doped Superconductor Eu2-xCexCuO4

Project Description:

Superconductivity is a phenomenon found in some materials showing zero electrical resistivity when they are cooled down to sufficiently low temperatures. The superconductor is a promising material for future applications, especially for energy-saving and high-performance power storage devices. The single-layer cuprates of high-temperature superconductors discovered in 1986 were called 214 cuprates. There are two types of 214 cuprates, namely, hole- and electron-doped cuprates. Some properties such as transport and magnetic properties were already clarified in hole-doped cuprates, while the information about those properties in electron-doped cuprates is still lacking. The possible reasons are some difficulties in preparing high-quality samples and controlling oxygen content in the samples of electron-doped cuprates.

The study of electron-doped cuprates has been of great interest in relation to the mechanism of superconductivity. The studies of physical properties through the partial substitution of non-magnetic impurities such as Zn for Cu in both systems are one of the important ways to elucidate the mechanism of superconductivity in 214 cuprates. Therefore, we propose to study the effects of partial substitution of non-magnetic impurity Zn for Cu to the magnetic properties in electron-doped superconducting cuprates of Eu2-xCexCu1-yZnyO4 (ECCZO).

During the 4 years of research, the polycrystalline samples of ECCZO will be synthesized with variations of x in the range between 0.09 and 0.25 with an impurity value of y = 0 - 0.10. XRD characterization and susceptibility measurements will be carried out to study various physical properties such as the structure and magnetic properties of the material. The target of output during 4 research are technological and scientific products. Technological products are in the form of superconducting materials and the findings of their physical properties, while scientific products are scientific publications in reputable international journals with quartiles 1 to 3.
