Science

Scientific Scope 1：This capability enables the quantitative measurement of weak magnetic signals in spintronic materials, empowered by a system that integrates parallel twin EPUs, beamline choppers, and lock-in amplification to enhance detection sensitivity by ~100x. The core aim is to build a bridge between microscopic properties (orbital/spin magnetic moments and local atomic/electronic structure) and macroscopic magnetic behavior. These insights are critical for laying the physical groundwork for intelligent material design.

Scientific Scope 2：Leveraging the 3-μm micro-focus capability of KB mirrors and the 5-ps phase-temporal resolution of XFMR, this platform enables temporal- and spatial-resolved  investigations of spin currents and spin waves in spin-orbit torque (SOT) and other prototype devices. These advances provide a critical tool for probing underlying mechanisms, such as spin current propagation (via coherent or thermal magnons) and the boundary conditions governing spin wave quantum effects.

Scientific Scope 3：The capability sample environment at liquid-helium temperature via dual-cooling technology, coupled with 20-nm spatial resolution of PEEM, allows this endstation to conduct magnetic domain structure imaging and spectroscopic mapping on emerging materials including 2D magnetic topological materials, their heterostructures and altermagnets, thereby providing a foundation for understanding their novel magnetic properties.
