The Annie K. Powell Lab

Annie K. Powell’s lab investigates the chemistry and physics of coordination compounds with unusual and controllable magnetic properties. The core research focus is the design, synthesis, and detailed characterization of molecular materials—particularly lanthanide-containing complexes—that display slow magnetic relaxation, strong anisotropy, and exotic spin states such as toroidal moments. A central theme of the lab is single-molecule magnetism (SMM), where individual molecules act as nanoscale magnetic units. The group explores how molecular structure, bridging ligands, radical components, and 3d–4f metal interactions influence magnetic anisotropy, dipolar coupling, and quantum tunneling of magnetization. To achieve this, the lab combines synthetic inorganic and coordination chemistry with a broad range of experimental techniques, including single-crystal X-ray diffraction, SQUID magnetometry, high-field EPR, Mössbauer spectroscopy, inelastic neutron scattering, and advanced spectroscopic methods. Experimental studies are closely supported by theoretical modeling and ab initio calculations. Beyond fundamental insight, this research is highly relevant to emerging technologies such as quantum information processing, high-density data storage, and molecular spintronics, where controlling spin states at the molecular level is crucial. The lab is well suited for students with interests in inorganic chemistry, materials chemistry, or molecular physics. Ideal candidates enjoy synthesis and characterization, are curious about structure–property relationships, and are motivated to work at the interface of chemistry, magnetism, and quantum science.
