||Barium calcium tungsten oxide (Ba2CaWO6) is known for its double perovskite-type crystal structure. The present study was designed to see the effect of biofield energy treatment on physical, atomic, and structural properties of Ba2CaWO6. In this study, Ba2CaWO6 powder sample was divided into two parts, one part was remained as untreated, denoted as control, while the other part was subjected to Mr. Trivedi’s biofield energy treatment and coded as treated. After that, the control and treated samples were analyzed using X-ray diffraction (XRD), surface area analyzer, Fourier transform infrared (FT-IR), and electron spin resonance (ESR) spectroscopy. The XRD data revealed that the crystallite size was decreased by 20% in the treated Ba2CaWO6 sample as compared to the control. The surface area of treated Ba2CaWO6 was increased by 9.68% as compared to the control sample. The FT-IR spectroscopic analysis exhibited that the absorbance band corresponding to stretching vibration of W-O bond was shifted to higher wavenumber from 665 cm-1 (control) to 673 cm-1 after biofield energy treatment. The ESR spectra showed that the signal width and height were decreased by 88.9 and 90.7% in treated Ba2CaWO6 sample as compared to the control. Therefore, above result revealed that biofield energy treatment has a significant impact on the physical and structural properties of Ba2CaWO6.
