1. a. b. We are concerned with discovering new magnetic and electrical properties of new systems. All measurements are performed on single crystals allowing the study of physics of new materials. We discovered several new phases with quantum spin liquid behavior. MnAl2S4 FeAl2S4 O Mo Crystal Growth of Intermetallics with Competing Magnetic InteractionsJulia Y.

This work was made possible with single crystals grown in our laboratory. Spin glass behavior can be attributed primarily to site disorder due to mixing of M2+ and Al3+ions and low dimensionality with geometrical frustration also playing a role – an example of material showing quantum effects. 100 μm Synthesis of Yb6Cr4Al43 Synthesis of YbCr2Al20
