The manipulation of magnetic properties by an electric field in magnetoelectric multiferroic materials has driven significant research activity, with the goal of realizing their transformative technological potential. Here, we review progress in the fund
Hard magnetic materials retain a large amount of residual magnetism after exposure to a magnetic field. These materials typically have coercivities, Hc, of 10 kA/m (125 Oe) to 1 MA/m (12 kOe). The materials at the high coercivity end of this range are known as permanent magnets. These...
This idea (permanent magnetism) was commonly believed a century ago. Because the temperature of the core is so high, permanent magnetism is not possible. Therefore, the magnetic field should decay, over tens of thousands of years. Since it does not, the field must be regenerating. Since the...
In this system, the amino groups on the hyperbranched cross-linker reacted with aldehyde groups to form dynamic imine bonds; the hyperbranched cross-linker endowed the material great shape memory behavior, and the soft and flexible chain structure also enhanced the toughness. The permanent shape ...
Magnetoresistance (MR) based biosensors are considered promising candidates for the detection of magnetic nanoparticles (MNPs) as biomarkers and the biomagnetic fields. MR biosensors have been widely used in the detection of proteins, DNAs, as well as th
Additionally, they can be manipulated by employing a permanent magnet, and the researchers consider that the heterodimer nanocomposite could also be useful as contrast agent for MRI applications. The hydrophobic heterodimer nanoparticles were simple prepared by growing Ag nanocrystals with tunable sizes on...
Most attention is paid to the results of the following investigations: first experimental observations of the appearance of "anomalous- ly bound" hydrogen in NdFeB permanent magnets during their brittle fracture in hydrogen environ- ments; the use of hydrogen vibrodecrepitation in the ...

Abstract Shape memory polymer composites (SMPCs) are a type of smart material that can change shapes under the stimulation of the external environment, and they have great potential in aerospace, biomedical, robotics, and electronic devices due to their advantages of high strength and toughness, li...
