Exploring New Metallic Quantum Spin Liquid in Intermetallic Compounds.
In: Pitt Momentum Fund 2023.
Abstract
Quantum spin liquids are a special type of magnets where the spins tend to order but never order. They have great potential in realizing quantum communication and the theory of high-temperature superconductivity, which are two of the long-term goals in physics and engineering. QSL state is normally found to exist in electrical insulators, and only very few of them were found not to contain oxygen and halogen due to their intrinsic insulating nature. However, this “rule of thumb” excludes a significant component of materials, i.e., intermetallics which are made by metallic or half-metallic elements and are usually metal. The aim of this proposal is to discover novel intermetallic QSL candidates from chemical perspectives. First, different synthetic methods will be employed to make new intermetallic magnets with special structural motifs that can host QSL state. Next, we will use XRD or SEM-EDS to obtain structural information of the new phases. Finally, we will employ the magnetometer to characterize their magnetic properties. Necessary doping studies can also be performed to induce insulating feature. This work can build a new platform for researchers to investigate QSL state in intermetallic systems, which can be connected to interesting quantum states, like unconventional superconductivity.
