X-ray diffraction of the samples was carried out using Bruker D8 Advance Twin-Twin equipment using Cu-Kα (1.5404 Å) radiation. Powdered samples were dispersed and pressed on the glass plate before taking XRD of the sample. Transmission electron microscopy images of the samples were taken using JEOL JEM 2100 HRTEM operating at 200 kV. Powdered samples were dispersed in ethanol and sonicated and were taken on a carbon grid before TEM measurements. Thermogravimetric analysis (TGA) was performed with a Perkin Elmer, Diamond TG/DTA in a nitrogen atmosphere in the temperature range 15–900 °C at 20 °C/min. Vibrating Sample Magnetometer measurements of the powder samples were performed using Quantum Design Dynacool PPMS in the field range ±50 KOe at 300 K. PL studies of the samples were investigated using an inVia Reflex Raman spectrometer attached with a laser of excitation wavelength 405 nm (Renishaw, UK, Model No. M-9836-3991-01-A).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
