Multicaloric effects in PbZr0.2Ti0.8O3 thin films with 90° domain structure
F. Wang et al 2017 EPL 118 17005
View abstract View article PDF
The multicaloric effects of a PbZr 0.2Ti 0.8O 3 thin film with 90° domain structure at room temperature are predicted using a phase-field simulation. The calculation results indicate that the giant negative multicaloric Δ T E, σ can reach −11 K which far exceeds the values associated with either elastocaloric or electrocaloric effects. In addition, the multicaloric effect is larger than the stress-mediated electrocaloric effect or electrically mediated elastocaloric effect, and the transition of the 90° domain structure to a monodomain greatly affects the caloric effects of PbZr 0.2Ti 0.8O 3 thin films.

Magnetic properties of (Ga,Mn)As (110) epitaxial films
Jialin Ma et al 2017 EPL 118 17003
View abstract View article PDF
Magnetic properties of (Ga,Mn)As films epitaxied on GaAs (110) substrates have been investigated. Both magnetic and magnetotransport measurements indicate dominant in-plane magnetic anisotropies for as-grown and annealed samples. Moreover, obvious in-plane spin reorientation transition upon the change of temperature has been observed for the as-grown samples, which disappears after annealing. The above phenomena are shown to be correlated with the competition between the cubic and the uniaxial magnetic anisotropic fields. The relative strengths of these two terms are quantitatively obtained by the planar Hall measurements and can be tuned by annealing. For all the annealed (Ga,Mn)As (110) films, a dominant [−110] uniaxial magnetic easy axis is found and the mechanism is discussed. Our work provides useful information for understanding the origin of magnetic anisotropies in (Ga,Mn)As films.

Loss of tension in electromechanical actuation of fiber-constrained viscoelastic dielectric elastomers
Junshi Zhang et al 2017 EPL 117 67004
View abstract View article PDF
Dielectric elastomers (DEs) under pure shear state can generate the giant deformation without the pull-in and snap-through instabilities. The pure shear state is usually achieved by using fibers to constrain the deformation in an in-plane direction. Since the DEs cannot support the compressed stress, the instability of loss of tension (LT) may occur in the fiber-constrained direction as the voltage-induced Maxwell stress increases. In this article, by incorporating the effects of different values of tensile force, applied voltage (including both step and ramp voltages), prescribed constrained deformation and viscoelasticity intensity, a viscoelastic model is employed to explore the instability of LT of fiber-constrained DEs with analysis of the electromechanical deformation and stress evolution.

Retrieval of charge mobility from apparent charge packet movements in LDPE thin films
Jia Meng et al 2017 EPL 117 67003
View abstract View article PDF
The charge packet phenomenon observed in polyethylene materials has been reported extensively during the last decades. To explain its movement, Negative Differential Mobility (NDM) theory is a competitive model among several proposed mechanisms. However, as a key concept of this theory, a sufficiently acute relationship between charge mobility and electric field has never been reported until now, which makes it hard to precisely describe the migration of charge packets with this theory. Based on the substantial negative-charge packet observations with a sufficiently by wide elect
