Ruihua Cheng

Ruihua Cheng is a Professor in the Department of Physics at Indiana University, specializing in experimental condensed matter physics with a focus on nanomagnetism and spintronics. Her research aims to understand magnetic phenomena in nanostructured materials for applications in spintronic devices and sensors through fabrication and in situ characterization.

Dr. Cheng's educational background includes:

• Ph.D. in Physics and Astronomy, University of Nebraska-Lincoln (2002)
• M.Sc. in Physics and Astronomy, University of Nebraska-Lincoln (2000)
• M.Sc. in Physics, Northern Jiaotong University, China (1996)
• B.Sc. in Physics, Northern Jiaotong University, China (1993)

Her research centers on geometric confinement effects in magnetic systems, examining how nanostructuring influences spontaneous magnetization, magnetic anisotropy, spin-orbital moments, and spin-dependent transport. Key methodologies include molecular beam epitaxial growth of nanodots/nanowires and characterization of hybrid ferromagnetic/semiconductor structures. Current investigations target quantum dots, magnetic single-electron transistors, and molecular magnets for ultra-high-density data storage.

Publications from 2008-2011 demonstrate consistent focus on magnetic nanostructures (Fe, Co, Ni systems), surface science of vicinal metals, and spin-transport phenomena. Recurring themes include antidot array configurations, ferroelectric polymer characterization, and STM-based single-molecule studies, reflecting strong experimental expertise in nanomagnetism with technological applications.

Dr. Cheng maintains active research through the Cheng Lab (website), though specific awards or grant funding details are not provided in available materials. Her work bridges fundamental physics with potential spintronic applications while utilizing advanced nanofabrication and characterization techniques.
