Title: Unraveling Single-Site Magnetism and Magneto-transport in Centrosymmetric Gd₂AlSi₃
Single crystals of the intermetallic compound Gd₂AlSi₃ were successfully grown using the flux growth technique. Structural characterization confirms that the compound crystallizes in a tetragonal structure. Despite the single-site occupancy of Gd, two successive antiferromagnetic phase transitions were identified through magnetic susceptibility, heat capacity, and transport measurements. The results reveal complex magnetic interactions with pronounced anisotropy, which play a crucial role in the magnetic ground state. These findings establish Gd₂AlSi₃ as a promising platform for investigating correlated electron phenomena in rare-earth intermetallics.
