“…In that many different ways have been done, including with the substitution of rare earth elements such as Nd, Eu, and Gd which is a magnetic material [5]. The substitution of rare earth element is not only used in YBCO superconductors but also use for substitution the Ca element on the BSCCO superconductors [6].…”

This study aims to determine the effect of adding sintering temperature to changes in crystal structure and magnetic properties of the Y-358 superconductor. The raw material consisting of Y2O3 (99.9%), BaCO3 (99.9%) and CuO (99.9%) were mixed in 3 days using a magnetic stirrer. Then heated at 100°C until crust. The calcination process was carried out at 600 for 3 hours and sintered at 850, 875, 900 and 925 o C for 10 hours each. From the X-Ray diffraction (XRD) result, the peak intensity of Y-358 superconductor increases with the addition of sintering temperature. The lowest peak intensity is 58 cps at 2θ of 86.4925 and the highest peak is 2041 cps at 2θ of 32.78. The addition of sintering temperature at 850, 875, 900 and 925 o C resulted in the addition of volume fraction, respectively 42.3%, 49.7%, 57.7% and 67.9%. The addition of sintering temperature also resulted in larger particle size, respectively 35.31, 47.72, 49.07 and 57.85 nm. The 3-day mixing treatment in the synthesis process resulted in a sample of nanometer size (nm) as seen in the TEM characterization results. The magnetic properties of the sample are known from the vibrating sample magnetometer (VSM) characterization results, showing the ferromagnetic properties with a magnetization saturation value of 0.08 emu/gr, the magnetization value of remanent of 0.02 emu/gr and the coercive force value of 684.12 Oe. The Fourier transform infrared spectroscopy (FTIR) characterization results show the absorption of OH groups in wave numbers 2814.14 and 3608.81 for samples calcined at 600°C and their intensity decreases with the addition of sintering temperature.

“…Research related to that substitution has been done by Suharta, et.al [6]. RE substitution is not only used in BSCCO superconductors alone, but some researchers also use to replace the Y element on the YBCO superconductors.…”

Synthesis of nano-particles Bi2Sr2(Ca1,5Nd0,25Gd0,25)Cu3Oz (BSCNGCO) superconductors has been successfully done by the wet mixing method. The aim of the study was to produce nanoparticles of BSCNGCO superconductors and study magnetic properties at room temperature. In this research, the raw material used in the formation of BSCNGCO superconductors is Bi2O3 (99.9%), SrCO3 (99.9%), CaCO3 (99.9%), CuO (99.9%), Nd2O3 (99.9%) and Gd2O3 (99.9%). The synthesis process was conducted by added with HNO3 and mixing by a magnetic stirrer to obtain a homogeneous solution, then continued with the calcination process at 450
