Abstract Controlling magnetism by an electric field is of critical importance for the future development ultralow-power electronic and spintronic devices. Progress has been made in electrically driven nonvolatile tuning magnetic states multiferroic heterostructures information storage industry, which exclusively attributed to ferroelectric-polarization-switching-induced interfacial charge effec...

Large magnetic-field-induced strain ~MFIS! of 22700 ppm has been obtained from the Heusler alloy Ni52Mn23Ga25 at 300 K. The temperature for structure transformation was confirmed by three types of magnetic measurements. A burst of MFIS up to 5400 ppm could be induced by rotating a steady field of 1 T. In the martensitic phase, the material have a high saturated magnetization of 66 Am/kg and a h...

Magnetic Barkhausen noise (MBN) technology is widely used to reveal the microscopic mechanism of magnetomechanical phenomena, but morphological transition induced by tension has not yet been confirmed experimental measurements. Here, we report a novel effect on morphology MBN signals due tensile stress with pre-introduced strain. We present power-law relation between critical for and degree str...

Anisotropic strain relaxation in Ga,Mn As nanostructures was studied combining time-resolved Kerr microscopy and ferromagnetic resonance techniques. Local resonance measurements on individual narrow stripes patterned along various crystallographic directions reveal that the easy axis of the magnetization can be forced perpendicular to the strain relaxation direction. Spatially resolved measurem...

Highly directional-dependent metal-insulator transition is observed in epitaxial double perovskite LaBaCo2O5.5+δ films. The film exhibit metallic along [100], but remain semiconducting along [010] under application of a magnetic field parallel to the surface of the film. The physical origin for the properties is identified as in-plane tensile strain arising from oxygen vacancies. First-principl...

In this study, the vibration behavior of functional graded (FG) circular and annular nanoplate embedded in Visco-Pasternak foundation and coupled with temperature change is studied. It is assumed that a uniform radial magnetic field acts on the top surface of the plate and the magnetic permeability coefficient of the plate along its thickness are assumed to vary according to the volume distribu...

In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...

Electric-field control of magnetism via an inverse magnetostrictive effect is alternative path toward improving energy-efficient storage and sensing devices based on a giant magnetoresistance effect. In this Letter, we report lateral electric-field driven strain-mediated modulation magnetotransport properties in Co/Cu/Py pseudo spin valve grown ferroelectric 0.7Pb[Mg 1/3 Nb 2/3 )]O 3 –0.3PbTiO ...

Magnetostriction, known as the ability of magnetic materials to expand or contract in response field, is a key property Fe-Ga alloys exploited various types transducers. Usually, thin films deposited on rigid substrates suffer from clamping effect that hinders propagation strain. Herein, with macroporous, not fully constrained, geometry are prepared by electrodeposition metallized silicon templ...
