Chemical Spin Patterning in Metal-Organic Frameworks
… In magnets, interactions between electron spins result in emergent properties with profound fundamental and technological implications. As metal-organic-frameworks (MOFs) are highly tailorable materials, this thesis will examine the utilization of MOF platforms to engineer bespoke spin …

Quantum simulations with 8̳8̳Sr+̳ ions on planar lattice traps
… experimental progress towards simulating quantum spin Hamiltonians with trapped SSSr+ ions on microfabricated planar lattice traps. These types of quantum simulations help solve exponentially complex quantum systems, which are challenging to current classical computers. Porras and Cirac's work has …

Chemical Correlation of Magnetic Permeability and Microwave Absorption in Spinel Ferrite Nanoparticles
Spinel ferrites (MFe₂O₄, where M = Mn²⁺, Co²⁺, Zn²⁺, etc.) are magnetic nanomaterials with tunable properties that are valuable for wireless communication, memory storage, and electronics. Their complex permeabilities that are governed by composition, particle size, and spin-orbit interactions play …

Synthesis, structure, and magnetic properties of spin-1/2 kagomé antiferromagnets
… a kagomé because they exhibit strong geometric spin frustration and are predicted to show no magnetic long-range ordering (LRO). The three broad classes of kagomé layered materials presented herein--covalently linked layers, hydrogen-bonded layers, and electrostatically linked layers--reflect …

Rapid materials discovery of ternary transition metal chalcogenides
… phase transitions via a complex interplay of spin, charge, lattice and orbitals degrees of freedom. Since the discovery of superconductivity in low-dimensional materials, there has been a growing thrust to understand the emergent phenomena that arise from strong electron correlations. This …

Molecular-based magnets constructed from cyanometalate building blocks
… and a wide range of metals with different spin states and oxidation states can be substituted into the lattice. The manganese compounds K2Mnn[Mnn(CN)6l, CsMnn[Mnm(CN)6]«V2H20, and Mnn3[Mnn(CN)6]»12H20 crystallize in face-centered cubic lattices with cell constants of 10.15, 10.69, and 10.62 …
