“…Another insight is provided by the link between the aspect ratio of a sample and its lag angle (α), [ 33 ] defined as:

α = \arcsin (ρ_{normalH} (ϕ)) - ϕ

Here, ϕ is the angle between the magnetic field and the y ‐axis, ρ H (ϕ) is the angular dependent Hall response. If the magnetization does not align along the orientation of the magnetic field, then there will be a finite angle between the total magnetization and the magnetic field.…”

A large transverse thermoelectric response, known as the anomalous Nernst effect (ANE) has been recently observed in several topological magnets. Building a thermopile employing this effect has been the subject of several recent propositions. Here, a thermopile is designed and built with an array of tilted adjacent crystals of Mn3Sn. The design employs a single material and replaces pairs of P and N thermocouples of the traditional design with hermaphroditic legs. The design exploits the large lag angle between the applied field and the magnetization, which is attributed to the interruption of magnetic octupoles at the edge of the xy‐plane. Eliminating extrinsic contact between the legs will boost the efficiency, simplify the process, and pave the way for a new generation of thermopiles.

The PI hysteresis model is established by applying weighted superposition of basic hysteresis operators, where the stop hysteresis operators and the play hysteresis operators are the basic hysteresis operators.…”

Since the hysteresis property inherently exists in the rubber material, it is necessary to deal with the control issues for the micro‐hand by considering the hysteresis property. Therefore, in this paper, the robust tracking control for the micro‐hand systems is discussed from the aspect of the Prandtl–Ishlinskii hysteresis property which is more applicable for the real applications. Firstly, a new model is obtained by combining the dynamic model of the micro‐hand with Prandtl–Ishlinskii hysteresis property. Secondly, a new stability condition based on bounded input and bounded output stability is proposed for the Prandtl–Ishlinskii hysteresis modeled micro‐hand system from two different cases. Thirdly, by designing the robust controllers based on the internal model control method, the tracking performance can be improved by eliminating the effect from the disturbance. Finally, simulation is used to further demonstrate the effectiveness of the proposed design scheme.
