Research Highlights

LEEM image montage showing magnetic domain evolution from 123 K to 225 K — Temperature evolution of magnetic domains (LEEM imaging, 123–225 K).
Direct visualization of domain morphology and contrast evolution across temperature, useful for identifying phase transitions and characteristic length scales.

Photograph of a high-field magnet experimental setup with cabling and instrumentation — High-field magnet experimental setup for synchrotron-based measurements.
Platform for temperature-dependent and magnetic field-dependent spectroscopy/diffraction with in situ control of sample environment and instrument alignment. The NJIT 10T magnet system is stationed at PIPOXS Beamline (ID2A) at CHESS (Cornell University).

Schematic of diamond anvil cell, sample chamber, and detector geometry for synchrotron X-ray diffraction — Diamond anvil cell (DAC) experiments and synchrotron X-ray diffraction geometry.
High-pressure approach to tune electronic and structural degrees of freedom, enabling pressure-dependent structure–property correlations.
