The mechanical properties of magnetic materials are instrumental for the development magnetoelastic theories and optimization strain-modulated devices. In particular, two-dimensional (2D) magnets hold promise to enlarge these concepts into realm low-dimensional physics ultrathin However, no experimental study on intrinsic archetypal 2D magnet family chromium trihalides has thus far been perform...

Since the structural mechanics of super magnetostrictive actuator (GMA) system involves problems related to viscoelastic damping materials, fractional order is more accurate than integer calculus characterize features in structure. In further investigate intrinsic mechanism and dynamical characteristics GMA system, equations nonlinear containing terms are established main resonance analyzed usi...

Active suspension is considered to be a good way improve the ride comfort of high-speed trains. According output index requirements train’s active suspension, giant magnetostrictive actuator(GMA) proposed. This mainly because materials(GMM) has characteristics fast response, large force and high energy conversion rate. It verified by experiments that proportional excitation current. found in ex...

Applications of magnetostrictive materials, such as sensors and energy-harvesting devices, generally involve the use dynamic deformation, i.e., piezomagnetic effect, induced by an exciting magnetic field H ac . However, this effect is rarely measured directly but commonly approximated strain der...

The present paper describes the work done at SLAC for the magnetostrictive wire spark chambers of SPEAR, LASS and the two-meter streamer chamber. All three are CAMAC systems based on the use of a time digitizer module with different interfacing techniques into three different computers (Sigma 5, PDP-9, PDP-11). Of particular interest is a display controller module that permits wide selection of...

A method is developed which allows to determine the first-order and the second-order magnetoelastic coefficients of a magnetic bulk material from the ab-initio calculation of the magnetocrystalline anisotropy energy as function of a prestrain ǫ0. Explicit results are given for bcc Fe, and they agree well with experimental data obtained from the magnetostrictive stress measurements for epitaxial...

This paper addresses the development of inverse compensation techniques for a class of ferromagnetic transducers including magnetostrictive actuators. If unaccommodated, the hys-teresis and nonlinear dynamics can produce severe loss of control authority and potential instabilities when the actuators are incorporated in control design. In this work, hysteresis is modeled through the domain wall ...
