Hysteresis motor is self-starting synchronous motor that uses the hysteresis characteristics of magnetic materials to make torque. There are different methods to model this kind of motor and take into account the magnetic hysteresis characteristic of the rotor hysteresis ring. In this investigation the application of complex permeability concept is implemented to model the hysteresis loop and t...

Composite films on the base of ZnO with different weight percentages of polypyrrole have been prepared using the hot pressing method and their current-voltage characteristics have been studied. Results show that the films have nonlinear varistor behavior and can be used to protect sensitive circuits from 110V up to 350V overvoltages. It is found that the higher the content...

Germanium nanowires (GeNWs) with p- and n-dopants were synthesized by chemical vapor deposition (CVD) and were used to construct complementary field-effect transistors (FETs). Electrical transport and X-ray photoelectron spectroscopy (XPS) data are correlated to glean the effects of Ge surface chemistry to the electrical characteristics of GeNWs. Large hysteresis due to water molecules strongly...

Here, we will discuss the electrical transport processes that occur within thin films of polymeric amorphous carbon, which possess a high resistivity of 10 V cm, a Tauc band gap of 2.6 eV, and a low defect density of 10 spins cm. Using current versus voltage measurements, we have shown that the current is space-charge-limited, with a mobility value of typically 10 cm V s. The implantation of bo...

In this paper, the states of liquid drops sitting on a horizontal elastic cyclically stretched and then weakened substrate were studied experimentally. A thin rubber band was used as substrate, glycerin liquid. multi-branch hysteresis drop detected. The number branches in can be adjusted by changing time program for stretching–loosening tension.

We investigated the electrical and structural properties of TbScO3 as an alternative gate dielectric. Rutherford backscattering spectrometry revealed a stoichiometric film while X-ray photo-electron spectroscopy indicated silicate formation at the interface. Capacitance-Voltage measurements resulted in well behaving C-V curves with no hysteresis and a low density of interface trap states in the...

The elastic constants of Nd3Se4 show an anomalous behaviour above and below Tc = 52 K. Band effects are assumed to be the origin of the softening of C' in the paramagnetic region. Below Tc extra shifts arise from magneto-elastic coupling. An elastic hysteresis is observed which is directly related to the magnetic hysteresis loop. The metallic rare earth chalcogenides of RE3X4 type have attracte...

Hysteresis has been widely recognized in the soil water relationship. In this paper, a detailed review of hysteresis was performed in relation to its models. So far, different models have been suggested to describe hysteresis in the water retention curve (WRC) that could be categorized into two main groups: conceptual and empirical models. The models in the first group are based on the domain t...
