    ABSTRACT Excitation of antiferromagnetic dynamics is at the core of ultrafast spintronics. Coherent excitation of antiferromagnetic magnons is typically monochromatic, confined at dispersion intersections between antiferromagnetic magnons and the excitation source. Broadband excitation can be enabled by introducing electron spins in an incoherent manner, albeit accompanied by high energy consumption from Joule heating. Here, we demonstrate a broadband excitation of antiferromagnetic dynamics of 2D antiferromagnet CrSBr without Joule heating, by Rayleigh‐type surface acoustic wave (R‐SAW). Incoherent magnons are efficiently excited via the angular momentum transfer from acoustic phonons, across a wide range up to the spin‐flop field. The collinear alignment between the Néel vector and phonon angular momenta induces strong excitation of magnons with high phonon dissipation, whereas orthogonal alignment suppresses dissipation, as revealed by R‐SAW transmission. Our work uncovers a mutual interplay between phonon transport and antiferromagnetic order parameters, offering a broadband, low‐loss route to manipulate antiferromagnetic dynamics.

    Abstract Magnetic memory based on spin‐orbit torque (SOT) is a promising candidate for the next‐generation storage devices. Materials that generate out‐of‐plane spin polarization ( σ z ) are highly desired and actively pursued as the SOT generator, due to its ability to achieve field‐free SOT switching of perpendicular magnetization. However, integrating σ z into perpendicular magnetic tunnel junction for efficient data writing is not realized. Here, utilizing σ z from antiferromagnetic spin Hall effect in Mn 2 Au, σ z ‐enabled field‐free SOT switching of perpendicular magnetic tunnel junctions is realized demonstrating a magnetic memory with both writing and reading electrically. The tunnel magnetoresistance ratio achieves 66% with a critical current density of 5.6 × 10 6  A cm −2 at room temperature. Such field‐free fully SOT switching is further directly confirmed by domain imaging via magneto‐optical Kerr effect microscopy. In addition to enabling field‐free switching, σ z is proposed to assist ultrafast and more efficient switching of perpendicular magnetization compared with conventional in‐planes ones, based on simulations. This research advances the application of out‐of‐plane SOTs and paves the way for high‐density, high‐speed, and low‐power magnetic memory.

    Abstract Negative capacitance effect in ferroelectric materials provides a solution to the energy dissipation problem induced by Boltzmann distribution of electrons in conventional electronics. Here, we discover that besides ferroelectrics, the antiferroelectrics based on Landau switches also have intrinsic negative capacitance effect. We report both the static and transient negative capacitance effect in antiferroelectric PbZrO3 films and reveal its possible physical origin. The capacitance of the capacitor of the PbZrO3 and paraelectric heterostructure is demonstrated to be larger than that of the isolated paraelectric capacitor at room temperature, indicating the existence of the static negative capacitance. The opposite variation trends of the voltage and charge transients in a circuit of the PbZrO3 capacitor in series with an external resistor demonstrate the existence of transient negative capacitance effect. Strikingly, four negative capacitance effects are observed in the antiferroelectric system during one cycle scan of voltage pulses, different from the ferroelectric counterpart with two negative capacitance effects. The polarization vector mapping, electric field and free energy analysis reveal the rich local regions of negative capacitance effect with the negative dP/dE and (δ2G)⁄(δD2), producing stronger negative capacitance effect. The observation of negative capacitance effect in antiferroelectric films significantly extends the range of its potential application and reduces the power dissipation further.
