Magnetic shape-memory effects in a crystal

Shape memory and ferromagnetic shape memory effects in single-crystal Ni2MnGa thin films

Magnetic Shape Memory Microactuators

By introducing smart materials in micro systems technologies, novel smart microactuators and sensors are currently being developed, e.g., for mobile, wearable, and implantable MEMS (Micro-electro-mechanical-system) devices. Magnetic shape memory alloys (MSMAs) are a promising material system as they show multiple coupling effects as well as large, abrupt changes in their physical properties, e....

Application of Shape Memory Alloys in Seismic Isolation: A Review

In the last two decades, there has been an increasing interest in structural engineering control methods. Shape memory alloys and seismic isolation systems are examples of passive control systems that use of any one alone, effectively improve the seismic performance of the structure. Characteristics such as large strain range without any residual deformation, high damping capacity, excellent re...

Magnetic shape memory: Magnetoelastic sponges.

news & views Nevertheless, a few hurdles must be overcome before SBA dielectrics will make a significant impact on large-scale transistor manufacturing. Perhaps the biggest problem at the moment is the slow response of the sodium ions to an external electric field. Consequently, the capacitance of the SBA films is reduced at higher frequencies. Solid-polymer electrolytes typically suffer from a...

Magnetization changes in Ni–Mn–Ga magnetic shape memory single crystal during compressive stress reorientation

Magnetization as a function of strain of a Ni48.5Mn30.8Ga20.7 single crystal during 9 MPa compressive loading test was obtained by means of vibrating coil magnetometry for different static magnetic fields up to 1.15 T. The dependency is monotonic, nonlinear and shows a small hysteresis. Maximum reversible change of magnetization is 30% for a 0.6 T field, and irreversible change of about 50% is ...
