Structural, Spectroscopic, and Magnetic Studies on Copper Tartrate Crystals

Abstract

Copper tartrate crystals were grown by the gel growth method and characterised by energy-dispersive X-ray (EDAX), scanning electron microscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-vis spectroscopy, Fourier transform infrared, photoluminescence (PL), electron paramagnetic resonance, and low-temperature magnetic studies in the temperature range 300–20 K. The XRD study confirmed the orthorhombic structure of the crystal and the XPS study established the Cu2+ ions in the crystal. UV-vis study deduced the energy gap as 2.15 eV, confirming the semiconducting nature, and Urbach energy as 0.4686 eV. PL showed the presence of Cu2+ vacancy-related defects. Low-temperature magnetic study confirmed the paramagnetic nature in the temperature range 300–77 K, and the crystal showed a weak ferromagnetic signal at 20 K, which is interesting. The magnetic field along with the low temperature caused an ordered spin orientation.

Tailoring Room Temperature Ferromagnetism and Observation of Electrolyte of Widest Potential Window in Gd0.75Se Nano Particles

“…2H 2 O] showed a ferromagnetic signal weak in nature at 17.5 K. Similarly, copper exists in a 2+ state in copper tartrate. It is paramagnetic up to 77 K. It shows weak ferromagnetic signal at 20 K, [ 13 ] although copper is paramagnetic. Gadolinium is reported [ 14 ] to be paramagnetic at ambient temperature and the ferromagnetic Curie point is 20 °C.…”
