Abstrakt:	This study analyzes the variations within LaCrO3 induced by diamagnetic gallium (Ga) substitution at the chromium (Cr) sites, exploring the consequential changes in both structural configuration and magnetic attributes. Through structural characterization employing X-ray diffraction (XRD) and scanning electron microscopy (SEM), the modified lattice parameters and crystalline structure resulting from Ga incorporation are revealed, shedding light on the structural and phase modifications within the material. The magnetic property investigations unveil the impact on the weak ferromagnetism intrinsic to LaCrO3 and in Ga substituted samples. Additionally, this research scrutinizes the consequential shifts in entropy resulting from Ga substitution, offering insights into the material's thermodynamic properties. The findings elucidate the intricate relationship between structural modifications and magnetic properties within perovskite oxides, providing valuable insights into the multifunctional effects of Ga substitution on LaCrO3.
