Electric field control of superconductivity at the LaAlO3/KTaO3(111) interface

Zheng Chen et al.

Summary: The study shows that the superconducting state at the oxide interface between LaAlO3 and KTaO3(111) can be tuned by applying a gate voltage across KTaO3, resulting in a dome-shaped dependence of transition temperature on gate voltage. The electric gating affects mobility more than carrier density. As the temperature decreases, the resistance saturates at the lowest temperature on both superconducting and insulating sides, indicating the emergence of a quantum metallic state associated with a failed superconductor and/or fragile insulator.

Electric Field Control of the Magnetic Weyl Fermion in an Epitaxial SrRuO3 (111) Thin Film

Weinan Lin et al.

Summary: Magnetic Weyl fermions originate from TRS-breaking in magnetic crystalline structures and can be effectively controlled by electric and magnetic fields. Electric field control of magnetic Weyl fermions has been demonstrated in SrRuO3 (111) thin films, showing promise for energy-efficient electronics. This work may stimulate further research on and manipulation of Weyl fermions in other magnetic materials.

Photoconductivity of the EuO-KTO Interface: Effect of Intrinsic Carrier Density and Temperature

Manish Dumen et al.

Summary: This study reveals the effect of light illumination on the transport properties of a two-dimensional electron gas formed at the conducting interface of EuO and KTaO3, showing that lowering carrier density increases photoresponse and photoresponse becomes faster and larger at low temperature. The observation suggests an interplay between carrier and phonon dynamics determines the photoresponse.

Summary: The study focuses on the investigation of multiferroic and ME properties of Ni-doped PZT materials, showing strong ME coupling. Although X-ray diffraction indicates a single-phase material, transmission electron microscopy reveals regions with and without Ni, suggesting the possibility of magnetoelectric coupling between two phases.

Experimental signatures of the chiral anomaly in Dirac-Weyl semimetals

N. P. Ong et al.

Summary: The chiral anomaly, originally studied in pion decay, has led to related effects in Dirac and Weyl semimetals, describing the conversion of left-moving fermions to right-moving ones in electric and magnetic fields. Recent experiments have explored this anomaly, particularly focusing on negative longitudinal magnetoresistance and potential current-jetting artifacts in Dirac-Weyl semimetals. The research extends to various experiments like non-local transport, thermopower, thermal conductivity, and optical pump-probe response, with future prospects involving improved LMR experiments and new investigations in thermal conductivity and optics.

Anisotropic magnetoresistance and planar Hall effect in (001) and (111) LaVO3/SrTiO3 heterostructures

Ruchi Tomar et al.

Summary: A two-dimensional electron gas at the interfaces of perovskite oxides has exhibited various emergent phenomena, including weak antilocalization, planar Hall effect, and anisotropic magnetoresistance. The (001)-oriented heterointerface shows a higher anisotropic magnetoresistance compared to the (111)-oriented heterointerface, with unique characteristics observed for both orientations. These phenomena can be linked to Fermi surface reconstruction due to orbital occupancy and polarization/hybridization.

Summary: The study reveals the presence of the Rashba effect in the EuO-KTaO3 system, indicating the formation of Rashba spin-split bands with two Fermi surfaces and a Berry's phase, along with strong spin-orbit coupling. Additionally, the observation of the two-fold planar Hall effect and anisotropic magnetoresistance suggests a possible band diagram near the Fermi surface.
