Hysteresis and memory effects in irradiated potassium blue bronzes
نویسندگان
چکیده
2014 Molybdenum blue bronzes exhibit below the Peierls transition time-dependent phenomena. These properties, which are related to the charge density wave instability, are often associated to the presence of defects. In this paper we show that the hysteresis observed during temperature cycling is amplified when defects are introduced by irradiation. We describe two new phenomena observed after a constant temperature relaxation : on cooling the resistance versus temperature curves show a plateau attributed to a fixed number of carriers ; on heating we observe a memory effect at the relaxation temperature.

Ion channeling in the quasi-one dimensional blue bronzes A0.30MoO 3 (A = K, Rb)
2014 We have measured backscattering yields of 1 MeV protons in the quasi-one dimensional blue bronzes Ka0.30MoO3 and Rb0.30MoO3 at temperatures between 50 and 350 K. Large hysteresis and time dependent effects involving long time scales are found. The measurements are discussed in terms of charge density wave domains and domain walls coupled to lattice defects.

متن کاملPinning of charge density waves in irradiated blue bronzes K 0.30MoO3 and Rb0.30MoO3
2014 Non linear conductivity due to the depinning of charge density waves has been studied in the Peierls distorted state of the blue bronzes K0.30MoO3 and Rb0.30MoO3 as a function of concentration of defects created by electron irradiation. The threshold electric field for the onset of non linearity is found to increase linearly with the defect concentration, as expected for strong pinning cen...

2014 In quasi-one dimensional inorganic conductors such as the transition metal trichalcogenides NbSe3, TaS3, the tetrachalcogenides (TaSe4)2I, (NbSe4)10/3I and the molybdenum blue bronzes A0.30MoO3 (A = K, Rb, T1) a new collective transport by the macroscopic sliding of a so-called charge density wave through the lattice has been reported. We review the structural and electronic properties of ...
متن کاملExperimental Hysteresis Identification and Micro-position Control of a Shape-Memory-Alloy Rod Actuator
In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind. The current study aims at developing a micro-position control system ...
متن کاملModeling SMA actuated systems based on Bouc-Wen hysteresis model and feed-forward neural network
Despite the fact that shape-memory alloy (SMA) has several mechanical advantages as it continues being used as an actuator in engineering applications, using it still remains as a challenge since it shows both non-linear and hysteretic behavior. To improve the efficiency of SMA application, it is required to do research not only on modeling it, but also on control hysteresis behavior of these m...
