Magnetic anisotropy at the interface between a thin metallic ferromagnet and an insulating oxide layer has been used to make devices with voltage-controlled switching [1-4]. Sharp switching thresholds have previously been reported for devices below 100 nm [3], but questions remain about the size dependence of the switching thresholds and the stability with respect to thermal fluctuations. Here a series...
Planar wire array Z pinches were carried out on the QiangGuang-I facility (1.3 MA, 100 ns). The effect of prepulse current and insulating coatings on the Z pinch behavior is investigated. Commonly there is a multichannel gas switch filled with 0.5 Mpa dry air between the transmission line and the MITL to cut off the prepulse current. By varying gas pressure filled in the switch, the parameters of...
A multi-layer lateral PCM with N-doped Sb70Te30 was proposed and demonstrated. Both current sweep and pulse mode dynamic resistance test show that multi states exist in the device, which can be used for multi-level data storage. Simulation shows the working mechanism of multi-level and confirms the experiment results. More intermediate states can be realized by increasing the cycles of N-doped Sb70Te30...
This paper presents a wireless distributed system to measure transient electromagnetic field in power substations. Taking advantage of flexible short-range wireless technique, the system allows flexible multi-node simultaneous measurement while is of compact size and low cost.
The widespread use of non-linear loads and power electronics converters has increased the generation of non-sinusoidal and non-periodic currents and voltages in power systems. Reactive power compensation or control is an important part of a power system to minimize power transmission losses. Given a modulation index, the switch times can be chosen to achieve the fundamental while eliminating specific...
