Magnetic properties of Gd3Cu3Sb4
Journal of Magnetism and Magnetic Materials(2022)
摘要
Here, we investigated Gd3Cu3Sb4 compound, with the focus on its magnetic structure. We performed magnetization and susceptibility measurements and determined X-ray photoelectron spectroscopy valence band spectra. We also performed a detailed density functional theory calculations. We found that collinear antiferromagnetic structure is preferred over the non-collinear one observed earlier in the analogue Ce3Cu3Sb4 compound. The calculated energy of the unit cell is lower, when assuming a collinear scenario, and magnetic measurements seem to also support this result.
