Synthesis, Crystal Growth, Magnetic and Transport Properties of
Ln-M-X (Ln=lanthanide, M=transition metal, X=In, Ga) Compounds
by Williams, Willa Maria  Abstract (Summary) ABSTRACT This
dissertation focuses on the structural stability, magnetic and
transport properties of ternary lanthanide compounds grown using
indium and gallium flux. Single crystals of TbRhIn5 were
synthesized using indium flux. TbRhIn5 is isostructural to the
well known LnnMIn3n+2 (n = 1, 2, ?; Ln = La, Ce; M = Rh, Ir) and
adopts the HoCoGa5 structure type and crystallizes in the space
group P4/mmm, Z = 1. Lattice parameters are a = 4.6000(6) Å and
c = 7.4370(11) Å, V = 157.29(6) Å3. A sharp antiferromagnetic
transition is observed at TN = 48 K for TbRhIn5. Single crystals
of SmPd2Ga2 have been synthesized by flux growth methods.
SmPd2Ga2 adopts the tetragonal space group I4/mmm, Z=2, with
lattice parameters, a = 4.2170(3) Å and c = 10.4140(3) Å. This
new material has physical properties similar to other Sm
intermetallics and has, most n
