background: nowadays, magnetic nanoparticles (mnps) have received much attention because of their enormous potentials in many fields such as magnetic fluid hyperthermia (mfh). the goal of hyperthermia is to increase the temperature of malignant cells to destroy them without any lethal effect on normal tissues. to investigate the effectiveness of cancer therapy by magnetic fluid hyperthermia, fe...

Magnetoelectric coupling in multiferroic heterostructures offers a promising platform for electric-field control of magnonic devices based on low-power spin-wave transport. Here, manipulation the amplitude and phase propagating spin waves ferromagnetic Fe film top ferroelectric BaTiO3 substrate is demonstrated experimentally. Electric-field effects this composite material system are mediated by...

Magnetic shape memory alloys display magnetic-field-induced strain (MFIS) of up to 10% as single crystals. Polycrystalline materials are much easier to create but display a near-zero MFIS because twinning of neighboring grains introduces strain incompatibility, leading to high internal stresses. Pores reduce these incompatibilities between grains and thus increase the MFIS of polycrystalline Ni...

Background: Giant magnetostrictive materials are increasingly proposed for smart material applications such as in sensors, actuators, and energy harvesting applications. However, reviewing the literature on this topic, the reader observes a large amount of variability in the reported properties that are typically generated from overall strain or point-value strain measurements obtained with str...

We report direct observation of controlled and reversible switching of magnetic domains using static (dc) electric fields applied in situ during Lorentz microscopy. The switching is realized through electromechanical coupling in thin film Fe(0.7)Ga(0.3)/BaTiO(3) bilayer structures mechanically released from the growth substrate. The domain wall motion is observed dynamically, allowing the direc...

Surface acoustic waves (SAWs) in the GHz frequency range are exploited for the all-elastic excitation and detection of ferromagnetic resonance (FMR) in a ferromagnetic-ferroelectric (Ni/LiNbO(3)) hybrid device. We measure the SAW magnetotransmission at room temperature as a function of frequency, external magnetic field magnitude, and orientation. Our data are well described by a modified Landa...

We evaluate the sound attenuation in a Weyl semimetal subject to magnetic field or pseudomagnetic associated with strain. Due interplay of intra- and inter-node scattering processes as well screening, fields generically reduce absorption. A nontrivial dependence on relative direction wave vector, i.e., dichroism, can occur materials nonsymmetric nodes (e.g., different Fermi velocities and/or re...
