Possible restoration of particle-hole symmetry in the 5/2-quantized Hall state at small magnetic field
Frédéric Mila, Loïc Jean Pierre Herviou
Motivated by the experimental observation of a quantized 5/2 thermal conductance at filling nu = 5/2, a result incompatible with both the Pfaffian and the anti-Pfaffian states, we have pushed the expansion of the effective Hamiltonian of the 5/2-quantized ...
AMER PHYSICAL SOC2023Hybridization driving distortions and multiferroicity in rare-earth nickelates
Nicola Marzari, Iurii Timrov, Michele Kotiuga, Luca Binci
For decades transition-metal oxides have generated a huge interest due to the multitude of physical phenomena they exhibit. In this class of materials, the rare-earth nickelates, RNiO3, stand out for their rich phase diagram stemming from complex couplings ...
College Pk2023Dipolar-stabilized first and second-order antiskyrmions in ferrimagnetic multilayers
Skyrmions and antiskyrmions are topologically protected spin structures with opposite vorticities. Particularly in coexisting phases, these two types of magnetic quasi-particles may show fascinating physics and potential for spintronic devices. While skyrm ...
2021Tunable cooperativity in coupled spin-cavity systems
We experimentally study the tunability of the cooperativity in coupled spin-cavity systems by changing the magnetic state of the spin system via an external control parameter. As a model system, we use the skyrmion host material Cu2OSeO3 coupled to a micro ...
AMER PHYSICAL SOC2021Magnetic dynamics across the in-field transition in Ca3Co2O6
Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Nagabhushan Ganesh Hegde
The discovery of multiple coexisting magnetic phases in the crystallographically homogeneous compound Ca3Co2O6 has stimulated ongoing research activity. In recent years the main focus has been on the zero-field-state properties, where exceedingly long time ...
AMER PHYSICAL SOC2020Two coupled chains are simpler than one: field-induced chirality in a frustrated spin ladder
Although the frustrated (zigzag) spin chain is the Drosophila of frustrated magnetism, our understanding of a pair of coupled zigzag chains (frustrated spin ladder) in a magnetic field is still lacking. We address this problem through nuclear magnetic reso ...
2020Field-induced reorientation of helimagnetic order in Cu2OSeO3 probed by magnetic force microscopy
Cu2OSeO3 is an insulating skyrmion-host material with a magnetoelectric coupling giving rise to an electric polarization with a characteristic dependence on the magnetic-field (H) over right arrow. We report a magnetic force microscopy imaging of the helic ...
AMER PHYSICAL SOC2020STEERABLE CATHETER WITH PORTIONS OF DIFFERENT STIFFNESS
Dario Floreano, Alice Tonazzini
A steerable catheter (10) comprises portions (100, 105) of different stiffness, having a proximal end (11), a distal end, a lumen extending there between, at least one magnet (20) at the proximal end (11), at least a magnetic field to influence the proxima ...
2019Triggered incommensurate transition in PbHfO3
We report a type of structural phase transitions in dielectric materials: the triggered incommensurate (IC) transition. We demonstrate evidence for such a transition in the perovskite antiferroelectric PbHfO3 by means of single-crystal x-ray diffraction, d ...
AMER PHYSICAL SOC2019Thermodynamic evidence of a second skyrmion lattice phase and tilted conical phase in Cu2OSeO3
Precision measurements of the magnetization and ac susceptibility of Cu2OSeO3 are reported for magnetic fields along different crystallographic directions, focusing on the border between the conical and the field-polarized state for a magnetic field along ...
