The structural and magnetic characterization in this series was first verified by x-ray diffraction and bulk magnetization measurements. The samples exhibit the known hexagonal perovskite structure (P63/mmc space group) and have a single magnetic phase according to magnetizationmeasurements. In this paper, the ferromagnetic ordering temperature for Cr evolves smoothly from a range of 68 K to 77 K for CeCrGe3 to a range of 91 K to 96 K for LaCrGe3 as La replaces Ce. Magnetization results indicate the formation of domain walls below the transition temperature for all Ce(1−x)LaxCrGe3 systems investigated. Neutron results indicate ordered magnetic Cr moments aligned along the c axis for the x = 1 LaCrGe3 system, as well as for x = 0.19, 0.43, and 0.58, which contrasts with the x = 0 CeCrGe3 where the moments order in the ab plane.114406-1 - 114406-11openAccessmagnetic propertiesintermetallic compoundsmagnetizationneutron dosimetryMagnetic and structural properties of the intermetallic Ce(1−x)LaxCrGe3 series of compoundsArtigo de periódico11510.1103/PhysRevMaterials.5.1144060000-0002-4499-5949https://orcid.org/0000-0002-4499-594953.7780.00
