Challenges In The Discovery And Characterization Of Magnetic Intermetallics, William A. Phelan
Challenges In The Discovery And Characterization Of Magnetic Intermetallics, William A. Phelan
LSU Doctoral Dissertations
The crystal growth and characterization of four families of compounds, LnFeSb3 (Ln = Pr, Nd, Sm, Gd, and Tb) and CeCo(Sb, Sn)3, Ln2Fe4Sb5 (Ln = La – Nd and Sm), LnCu2(Al,Si)5 (Ln = La and Ce), and Ln(Cu,Al,Ga)13 (Ln = La – Pr and Eu), are presented in this dissertation. Special emphasis is placed on describing their structure-magnetic properties correlations. Discoveries and studies of these systems were motivated by their structurally related predecessors, which are comprised of complex structural subunits and exhibit unusual physical properties. The magnetic behaviors exhibited by a selection of these intermetallics include the large magnetoresistances and …

LSU Doctoral Dissertations
The focus of the research presented herein was to grow single crystals of Ln-M-X (Ln = lanthanide; M = Ti-Cr, Cu, Mo, Pd; X = Al, Ga) intermetallic compounds and to characterize their crystal structures and physical properties. Overall, the flux growth technique facilitated a detailed analysis of previously known structure-types (LnM2Al20 (Ln = La, Ce, Pr, Yb; M = Ti, V, Cr), Ln6M4Al43 (Ln = Gd, Yb; M = Cr, Mo), and Yb2Pd3Ga9), as well as the synthesis and characterization of new compounds (LnCrxGa3 (Ln = Ho, Er; x ~ 0.13), YbCr2Al20-xFex (x ~ 0.2), Ln(Cu,Al,Ga)13-x, and Ln2PdGa12 (Ln …
