Using a Ginzburg-Landau model for the magnetic degrees of freedom with coupling to disorder, we demonstrate through simulations the existence of stripelike magnetic precursors recently observed in Co-Ni-Al alloys above the Curie temperature. We characterize these magnetic modulations by means of the temperature dependence of local magnetization distribution, magnetized volume fraction, and magn...

Without whom this would never have been possible iv ACKNOWLEDGEMENTS This project would not have been possible without the support of many people, first and foremost my parents. Also, many thanks to my adviser, Dr. Yogendra K. Joshi, who read my numerous revisions and helped make sense of the confusion. Moreover, thanks to my committee members, Dr. Aaron Wemhoff and Dr. Satish Kumar, who offere...

A new method is presented for accounting for microstructural features of flowing complex fluids at the level of mesoscopic, or coarse-grained, models by ensuring compatibility with macroscopic and continuum thermodynamics and classical transport phenomena. In this method, the microscopic state of the liquid is described by variables that are local expectation values of microscopic features. The...
