SOME NEW MATERIALS REAL2GA2 AND THEIR NMR AND X-RAY ABSORPTION STUDIES
No full textNew ternary rare earth intermetallic compounds crystallizing in the ThCr<SUB>2</SUB>Si<SUB>2</SUB> type structure viz., LaAl<SUB>2</SUB>Ga<SUB>2</SUB>, PrAl<SUB>2</SUB>Ga<SUB>2</SUB>, NdAl<SUB>2</SUB>Ga<SUB>2</SUB>, EuAl<SUB>2</SUB>Ga<SUB>2</SUB> and YbAl<SUB>2</SUB>Ga<SUB>2</SUB> are reported. The quadrupole coupling constant of <SUP>27</SUP>Al has been measured for all these samples. The Knight shift of <SUP>171</SUP>Yb in YbAl<SUB>2</SUB>Ga<SUB>2</SUB> is found to be very small (⋍0%) and almost temperature independent. The positions of the L<SUB>3</SUB>-absorption edge of Eu and Yb in EuAl<SUB>2</SUB>Ga<SUB>2</SUB> and YbAl<SUB>2</SUB>Ga<SUB>2</SUB> have been measured. These results suggest that Eu and Yb are divalent in character
