Adaptive hard and tough mechanical response in single-crystal B1 VNx ceramics via control of anion vacancies
A. B. Mei, H. Kindlund, E. Broitman +4
High hardness and toughness are generally considered mutually exclusive properties for single-crystal ceramics. Combining experiments and ab initio molecular dynamics (AIMD) atomis…
Imaging uncompensated moments and exchange-biased emergent ferromagnetism in FeRh thin films
Isaiah Gray, Gregory M. Stiehl, John T. Heron +5
Uncompensated moments in antiferromagnets are responsible for exchange bias in antiferromagnet/ferromagnet heterostructures; however, they are difficult to directly detect because…
Local Photothermal Control of Phase Transitions for On-demand Room-temperature Rewritable Magnetic Patterning
Antonio B. Mei, Isaiah Gray, Yongjian Tang +6
The ability to make controlled patterns of magnetic structures within a nonmagnetic background is essential for several types of existing and proposed technologies. Such patterns p…
Discovery of Ordered Vortex Phase in Multiferroic Oxide Superlattices
Antonio B. Mei, Ramamoorthy Ramesh, Darrell G. Schlom
Ferroics, characterized by a broken symmetry state with nonzero elastic, polar, or magnetic order parameters , are recognized platforms for staging and manipulating topolo…
Effects of surface vibrations on interlayer mass-transport: ab initio molecular dynamics investigation of Ti adatom descent pathways and rates from TiN/TiN(001) islands
D. G. Sangiovanni, A. B. Mei, D. Edström +4
We carry out density-functional ab initio molecular dynamics (AIMD) simulations of Ti adatom (Tiad) migration on, and descent from, TiN <100>-faceted epitaxial islands on TiN(001)…
