Momentum-space spin texture induced by strain gradient in nominally centrosymmetric SrIrO films.

Spin texture in -space is a consequence of spin splitting due to strong spin-orbit coupling and inversion symmetry breaking. It underlies fertile spin transport phenomena and is of crucial importance for spintronics. Here, we observe the spin texture in -space of nominally centrosymmetric SrIrO grown on NdGaO (110) substrates, using non-linear magnetotransport measurements.

Evidence for Two-Dimensional Weyl Fermions in Air-Stable Monolayer PtTe.

The Weyl semimetals represent a distinct category of topological materials wherein the low-energy excitations appear as the long-sought Weyl Fermions. Exotic transport and optical properties are expected because of the chiral anomaly and linear energy-momentum dispersion. While three-dimensional Weyl semimetals have been successfully realized, the quest for their two-dimensional (2D) counterparts is ongoing.

Magnetic field filtering of the boundary supercurrent in unconventional metal NiTe-based Josephson junctions.

Topological materials with boundary (surface/edge/hinge) states have attracted tremendous research interest. Additionally, unconventional (obstructed atomic) materials have recently drawn lots of attention owing to their obstructed boundary states. Experimentally, Josephson junctions (JJs) constructed on materials with boundary states produce the peculiar boundary supercurrent, which was utilized as a powerful diagnostic approach.

Large Spin Hall Conductivity and Excellent Hydrogen Evolution Reaction Activity in Unconventional PtTe Monolayer.

Two-dimensional (2D) materials have gained lots of attention due to the potential applications. In this work, we propose that based on first-principles calculations, the (2 × 2) patterned PtTe monolayer with kagome lattice formed by the well-ordered Te vacancy (PtTe) hosts large and tunable spin Hall conductivity (SHC) and excellent hydrogen evolution reaction (HER) activity. The unconventional nature relies on the 1 @ 1 band representation of the highest valence band without spin-orbit coupling (SOC).

Thermoelectric properties of two-dimensional magnet CrI.

The thermoelectric, phonon transport, and electronic transport properties of two-dimensional magnet CrI are systematically investigated by combining density functional theory with Boltzmann transport theory. A low lattice thermal conductivity of 1.355 W mK is presented at 300 K due to the low Debye temperature and phonon group velocity.

Multiferroic LaPbFeO ceramics: Ferroelectricity, ferromagnetism and colossal magneto-capacitance effect.

The mutual control of the electric and magnetic properties of a multiferroic solid is of fundamental and great technological importance. In this article, the synthesis procedure of LaPbFeO ceramics was briefly described and the data acquired for the materials characterization is presented. This data article is related to the research article-Acta Mater.

Magnetoelectric Response in Multiferroic SrFe12O19 Ceramics.

We report here realization of ferroelectricity, ferromagnetism and magnetocapacitance effect in singleSrFe12O19ceramic at room temperature. The ceramics demonstrate a saturated polarization hysteresis loop, two nonlinear I-V peaks and large anomaly of dielectric constant near Curie temperature, which confirm the intrinsic ferroelectricity of SrFe12O19 ceramicswith subsequent heat-treatment in O2atmosphere. The remnant polarization of the SrFe12O19 ceramic is estimated to be 103μC/cm2.
