Abstract:TbRh2Ge2 orders antiferromagnetically in the AFI type structure with a magnetic moment of 9.4(3)μB at 4.2 K localized on the Tb3+ ion. TbRu2Ge2 exhibits a square modulated magnetic structure with moments aligned along the c-axis of the crystallographic unit cell. The magnitude of the magnetic moment localized on the Tb3+ ion is 9.1(1)μB at 4.2 K.
