We report high-resolution capacitance dilatometry studies on the uniaxial length changes in a NdB$_4$ single crystal. The evolution of magnetically ordered phases below $T_{\rm N}$= 17.2~K (commensurate antiferromagnetic phase, cAFM), IT}$= 6.8~K (intermediate incommensurate IT), and LT}$= 4.8~K (low-temperature LT) is associated with pronounced anomalies thermal expansion coefficients. data im...

The development of multifunctional and biocompatible microrobots for biomedical applications relies on achieving controllable locomotion. Here we describe the conditions that allow homogeneous magnetoelastic membranes composed superparamagnetic particles to swim through viscous fluids. By solving equations motion, find dynamical modes circular in precessing magnetic fields, which are found actu...

We study the asymptotic behavior, in sense of [Formula: see text]-convergence, a thin incompressible magnetoelastic plate, as its thickness goes to zero. focus on linearized von Kármán regime. The model features mixed Eulerian–Lagrangian formulation, magnetizations are defined deformed configuration.

گرافن ابررسانای طبیعی نیست اما افرادی بودند که لایه های ابررسانایی بوسیله لایه نشانی یک ابررسانا برروی یک لایه گرافن بر پایه گرافن تولید کرده اند ، به طوری که علاوه بر جفت شدگی معمول s-wave دیگر جفت شدگی های غیر معمول نیز با روش مجاورت یک ابرسانای غیر معمول نظیر ابررساناهای دما بالا قابل دسترسی خواهد بود. در نتیجه توجهات خاصی به تاثیر جفت شدگی های غیر معمول در انتقالات کوانتومی در اتصالات ابر ر...

Magnetoelastic coupling in the quantum magnet [Ni(HF2)(pyrazine)2]SbF6 has been investigated via vibrational spectroscopy using temperature, magnetic field, and pressure as tuning parameters. While pyrazine is known to be a malleable magnetic superexchange ligand, we find that HF2- is surprisingly sensitive to external stimuli and is actively involved in both the magnetic quantum phase transiti...

High aspect-ratio Fe nanostrips are known to reversibly switch from a single-domain magnetic state to a multidomain diamond pattern as a function of temperature (T) and width. This magnetic bistability can be understood by the temperature-dependent balance between magnetocrystalline, shape and magnetoelastic anisotropies and has potential applications in magnetic logic devices. However, as Fe n...

Current model-independent control techniques are limited, from a practical standpoint, by their dependence on a precontrol learning stage. Here we use a real-time, adaptive, model-independent ~RTAMI! feedback control technique to control an experimental system — a driven magnetoelastic ribbon — in its nonchaotic and chaotic regimes. We show that the RTAMI technique is capable of tracking and st...
