High sensitivity magnetometer to study magnetic textures and topology in quantum materials
Abstract
Quantum materials display a wealth of emergent properties, including unconventional superconductivity, Kondo physics, unconventional magnetism, etc, resulting from competing energy states. Recent years have added topology as a new variable to these competing electron and spin interactions, based on which new classes of materials are predicted- Kondo-Weyl fermions, Kramers-Weyl or multifold degenerate fermions, etc. Unconventional states of matter emerge near magnetic order, making the magnetic characterization of new candidate material a crucial first step. This proposal requests funds for the acquisition of a sensitive (SQUID) magnetometer that is paramount to characterizing the different classes of materials studied in the PI’s lab. In addition to the unconventional topological fermions (Kramers-Weyl or multifold degenerate), which are the basis of an ongoing project funded by AFOSR, the research that this magnetometer will enable includes real space topological spin texture systems, Kondo materials, itinerant magnets, etc. Students and postdocs operating this instrument will gain valuable training in magnetic property measurements, and in particular in low-temperature measurements afforded by the iHelium3 capability (T greater than 0.5 K).
