ysteresis arises in diverse applications, including structural mechanics, aerodynamics, and electromagnetics [1]–[4]. The word “hysteresis” connotes lag, although this nomenclature is misleading since delay per se is not the mechanism that gives rise to hysteresis. As discussed in [5], hysteresis is a quasi-static phenomenon in which a sequence of periodic inputs produces a nontrivial input-out...

Using a Ginzburg–Landau–Devonshire type model, the pyroelectric property and hysteresis loop are studied for a composite ferroelectric thin film that contains an insertion of a different type of ferroelectric material in parallel connection with the host ferroelectric film material. If these two types of ferroelectric materials are polarized along the same direction, there are two peaks occur i...

A hysteresis model with dipole interaction: one more devil-staircase. Abstract Magnetic properties of 2D systems of magnetic nanoobjects (2D regular lattices of the magnetic nanoparticles or magnetic nanostripes) are considered. The analytical calculation of the hysteresis curve of the system with interaction between nanoob-jects is provided. It is shown that during the magnetization reversal s...

Hyperpolarization-activated, cyclic nucleotide-gated (HCN) ion channels are important for rhythmic activity in the brain and in the heart. In this study, using ionic and gating current measurements, we show that cloned spHCN channels undergo a hysteresis in their voltage dependence during normal gating. For example, both the gating charge versus voltage curve, Q(V), and the conductance versus v...

Magnetic and magneto-optical properties were measured at room temperature in the Mn-diffused surface layer of a CdGeP2 single crystal. The magnetization curve measured using VSM clearly shows a ferromagnetic hysteresis loop with Hc=0.4 kOe superposed on the diamagnetic component. The ferromagnetic Curie temperature was determined as 320 K from the magnetization vs. temperature curve. The magnet...

Cobalt ferrite or CoFe2O4 has unique physical and magnetic properties depend on its synthesis method. The application of cobalt ferrite as nanomedicine material become more interesting, however analysis on physical and magnetic properties based on synthesis method have not been discussed. The cobalt ferrite in this research was synthesised using two different methods: the ...

The objective of this paper is to study the performance of a sixth order polynomial approach to model hysteresis behaviour of a magnetorheological (MR) damper under harmonic excitations. The polynomial model is developed based on curve fitting from the experimental results and consists of a pair subsystem namely positive and negative acceleration which correspond to the upper and lower curves. ...

We use Hoffmann's suggestion [Hoffmann, G. W. (1986) J. Theor. Biol. 122, 33-67] of hysteresis in a single neuron level and determine its consequences in a synchronous network made of such neurons. We show that the overall retrieval ability in the presence of noise and the memory capacity of the network in the present model are better than in conventional models without such hysteresis. Second-...
