A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum wave, introduced more than nine decades ago, has always been manipulated through dipoles, (i.e., timereversal symmetry). Here, we report experimental observation chiral-spin transport multiferroic BiFeO3, where is controlled by reversing ferroelectric polarization spatial inversion The ferroelectrically magnons produce an unprecedented ratio up to...
The three-dimensional dynamic response of a double articulated offshore loading structure to noncollinear waves and steady current is studied for various varying directions. governing equations motion are derived by the Lagrange’s method where wave forces computed modified form Morison’s equation which takes account relative water particles with respect oscillating structure. resulting highly nonlinear solved using block integration method. results predict complex whirling oscillations current.

Quantized anomalous Hall effects (QAHEs) occur in remarkable electronic states which possess not only quantized signals but some cases regions of dissipationless electron transport. The initial demonstrations a QAHE magnetically-doped topological insulator (TI) required temperatures below 100 mK, and since then major focus the field has been to increase temperature scale. Here, we report up 10 K (in what is known as parity anomaly state) TI/magnet bilayers made by mechanical assembly, rather...
