SQUID Magnetic Properties Measurement System
Abstract
This Defense University Research Instrumentation Program (DURIP) proposal is to acquire a SQUID Magnetic Properties Measurement System (MPMS) to be used in research and research training. This instrument will primarily enable the AFOSR research project (FA9550-22-1-0389) titled Coherent Transport of Energy and Information in 2D Superatomic Crystals (PI- Nuckolls; co-PIs- Roy, Zhu and Delor), funded through the Molecular Dynamics and Theoretical Chemistry program. The overall objective of this project is to engineer a new class of quantum systems based on superatomic materials, a class of ultra-manipulable and hierarchical structures whose initial discovery and subsequent development was supported by the AFOSR. These superatomic materials have functional building blocks that can be individually addressed to tune their electronic, nuclear and spin degrees of freedom with unprecedented control. The SQUID MPMS to be purchased with this DURIP will make possible a wide range of ultra-sensitive, magnetic and magnetotransport measurements for correlative studies. These capabilities will be critical at every step of the project, from understanding the magnetic properties of the superatoms, to characterizing the superatomic materials, van der Waals (vdW) magnets and heterostructures created by the team. The SQUID MPMS will also enable another DoD research project led by Zhu and Roy, New Mechanisms Towards Enhanced IR photon Detection in Multifunctional 2D Semiconductors , funded through the ARO program on Electronic Sensing (W911NF2310056). The overall objective of this proposal is to realize enhanced IR photon detection based on novel physical mechanisms in new multifunctional vdW semiconductors. In particular, this project aims at understanding the transduction of IR photons to magnons by developing a new family of vdW magnetic semiconductors in which magnons and excitons are strongly coupled. The realization of this aim requires a broad range of ultra-sensitive magnetic and magnetooptical measurements, which will be made possible by the purchase of the SQUID magnetometer through this DURIP. The acquisition of a new SQUID MPMS would significantly accelerate our progress in these DoD-funded projects by allowing us to investigate the magnetic properties of new superatomic materials This SQUID MPMS will fill the research needs of the 4 PIs on the AFOSR award, and will be transformative for many research programs at Columbia. From an educational and training perspective, this instrument will allow students and postdocs working on these projects the opportunity to learn hands-on how to measure the magnetic properties of molecules and materials.
