Complex metal oxides are a diverse and highly versatile class of materials that can exhibit scientifically and technologically important behaviors ranging from magnetism to piezoelectricity. New technologies and new fields of applications can be realized by expanding the scope of available ionic compositions and increasing the geometric complexity of nanostructures formed from crystalline oxide materials. IRG 2 focuses on probing the synthesis of oxides, increasing the range of available oxide compositions, and forming unique nanostructures – directions that are each enabled by use of novel transformations from the amorphous to crystalline form. This process of solid phase epitaxy, or SPE, allows the crystallization of materials that cannot be made through conventional processing techniques and provides the freedom to develop new materials and explore new properties.

Roemig Wins Best Poster Award at Pittsburgh Diffraction Conference
Simon Roemig's poster presenting research resulting from a collaboration between the Wisconsin MRSEC and the Wisconsin-Puerto Rico Partnerships for Research and Education in Materials (PREM) was presented with the Chung Soo Yoo Best Poster award at the 79th Annual Pittsburgh Diffraction Conference at Argonne National Laboratory in October 2022.

(2022) Computationally Designed Synthesis of Complex Oxide Materials
The useful properties of chemical compounds are determined by the elements from which they are made and the arrangement of the atoms. However, there are often several ways atoms of the same elements can be arranged to form a solid. Wisconsin MRSEC researchers are particularly interested in a series of compounds formed from rare-earth elements and iridium. One phase, Pr2Ir2O7, is of particular interest because it exhibits novel magnetic phenomena and can open new opportunities in the field of quantum materials.

(2022) Nanoscale Oxide Solid Phase Epitaxy
The crystallization of complex oxides can be templated by a crystalline seed. Nanoscale crystallization environments lead to the possibility that this process can be employed to create precise arrays of nanoscale materials for electronic, magnetic, and optical applications.

Wisconsin MRSEC Researchers Develop New Cutting-Edge Tool for Materials Discovery
A team of researchers from the Wisconsin Materials Research Science and Education Center (MRSEC) at the University of Wisconsin–Madison has designed, constructed, and implemented a new, highly specialized piece of research equipment that can be used to visualize the real-time formation and growth of tiny crystals of novel materials. The unique perspective provided by this approach provides access to new ways to discover and develop materials relevant to electronics, optics, and magnetic applications.
