Light‐Modulated Exchange Bias in Multiferroic Heterostructures

Electron, EarlyView.
In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Cross‐entropy method for distribution power systems reconfiguration

Engineering Reports, 2019
Cross‐entropy (CE) is a powerful simulation method for the solution of continuous and combinatory optimization problems. The work presented here utilizes the CE method for the optimal topology of distribution power systems (DPSs).

Reconfigurable Logic Operation of MoTe2 Homojunction Enabled by Staggered Double‐Sided Contacts

Electron, EarlyView.
A gap adjacent to an electrode in the MoTe2 SDC transistor enables polarity reconfiguration, switching between p‐type and n‐type depending on bias polarity. This reconfiguration is ensured when the absolute bias voltage is less than the gate voltage, yielding a near‐ideal subthreshold swing of 67.6 mV/dec and on/off ratios of 104–106.
