Crystallization of GeO2 thin films into alpha-quartz: from spherulites to single crystals
Silang Zhou, Jordi Antoja-Lleonart, Pavan Nukala +3
Piezoelectric quartz SiO2 crystals are widely used in industry as oscillators. As a natural mineral, quartz and its relevant silicates are also of interest of geoscience and minera…
Guidelines for the stabilization of a polar rhombohedral phase in epitaxial Hf0.5Zr0.5O2 thin films
Pavan Nukala, Yingfen Wei, Vincent de Haas +3
The unconventional Si-compatible ferroelectricity in hafnia-based systems, which becomes robust only at nanoscopic sizes, has attracted a lot of interest. While a metastable polar…
Structure and magnetic properties of epitaxial CaFe2O4 thin films
Silvia Damerio, Pavan Nukala, Jean Juraszek +3
CaFe2O4 is a highly anisotropic antiferromagnet reported to display two spin arrangements with up-up-down-down (phase A) and up-down-up-down (phase B) configurations. The relative…
Observation of the Magnon Polarization
Y. Nambu, J. Barker, Y. Okino +12
We measure the mode-resolved direction of the precessional motion of the magnetic order, i.e., magnon polarization, via the chiral term of inelastic polarized neutron scattering sp…

The band inversion in topological phase matters bring exotic physical properties such as the emergence of a topologically protected surface states. They strongly influence the surf…
Magneto-ionic control of spin polarization in magnetic tunnel junctions
Yingfen Wei, Sylvia Matzen, Cynthia P. Quinteros +4
Magnetic tunnel junctions (MTJs) with Hf0.5Zr0.5O2 barriers are reported to show both tunneling magnetoresistance effect (TMR) and tunneling electroresistance effect (TER), display…
BaTiO3 thin films as transitional ferrroelectrics with giant dielectric response
A. S. Everhardt, T. Denneulin, A. Gruenebohm +9
Proximity to phase transitions (PTs) is frequently responsible for the largest dielectric susceptibilities in ferroelectrics. The impracticality of using temperature as a control p…
Quantum thermodynamics of complex ferrimagnets
Joseph Barker, Gerrit E. W. Bauer
High-quality magnets such as yttrium iron garnet (YIG) are electrically insulating and very complex. By implementing a quantum thermostat into atomistic spin dynamics we compute YI…
Periodicity doubling cascades: direct observation in ferroelastic materials
Arnoud S. Everhardt, Silvia Damerio, Jacob A. Zorn +6
Very sensitive responses to external forces are found near phase transitions. However, phase transition dynamics and pre-equilibrium phenomena are difficult to detect and control.…
Resolving hydrogen atoms at metal-metal hydride interfaces
Sytze de Graaf, Jamo Momand, Christoph Mitterbauer +2
Hydrogen as a fuel can be stored safely with high volumetric density in metals. It can, however, also be detrimental to metals causing embrittlement. Understanding fundamental beha…
