The Progress in Magnetic Regulation of Flexible Magnetic Films Flexible electronic devices have the advantages of flexibility, easy portability, and potential low-cost manufacturing. They have important application prospects in medical, information, and energy fields, and have attracted widespread attention. The most ideal flexible electronic devices, such as flexible wearable devices, require all components to be [...]
Progress in the Study of Unusually Large Anisotropic Magnetoresistance Effects Our latest findings were published on August 25, 2009, in the Proceedings of the National Academy of Sciences. In cooperation with the National Institute of Materials Science of Japan, the Institute of Physics of the Chinese Academy of Sciences, Florida International University, and Louisiana State [...]
Progress in Stress Controlling Magnetic Anisotropy of Flexible Magnetostrictive Thin Films Magnetostrictive material Fe81Ga19 alloy has the advantages of low saturation field (~100 Oe), good ductility, and moderate amount of stretching (~350 ppm), and has broad application prospects in the field of sensors and actuators. In microelectromechanical systems as well as multifunctional composites, it is [...]
Research Progress in Flexible Magnetic Sensing Thin Film Materials and Devices The rapid development of flexible smart wearable devices puts forward the requirements for the flexibility of magnetoelectric functional devices. Due to the inverse magnetostrictive properties of magnetic materials, the stress/strain generated by the bending or stretching state can change the magnetic anisotropy of the [...]
New Progress in the Field of Magnetron Electronic Structures The application of an external magnetic field can control the electrical polarization, light polarization, temperature, geometry and other macroscopic physical properties of magnetic materials, that is, to achieve magnetoelectric, magneto-optical, magneto-caloric, and magneto-elastic effects. These effects constitute the physical basis of magnetic functional devices such as [...]
Progress in the Study of Topological Magnetic Structure Mechanism of Graphene/Ferromagnetic Metal Interface Magnetic skyrmions, a topologically protected magnetic vortex structure (as shown in Figure 1), are very suitable for applications in information storage, logic operations or neural network technology because they can be nanometer-sized, non-volatile and easy to drive. The field is a hot [...]
What is Ferromagnetic Paper? Ferromagnetic paper is formed by impregnating ordinary paper or newspaper with "magnetic nanoparticles". It can be used to make low-cost "micro-motors" for surgical instruments, tiny tweezers to study cells, tiny robots and tiny speakers. At present, the researching people will also ferromagnetic origami paper, to study more complicated design. Ferromagnetic paper [...]
Magnetic Particle Examination Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as “a term applied to materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities [...]
How do Magnetic Filters Work? While a large number of configurations exist, most magnetic filters work by producing a magnetic field or loading zones that collect magnetic iron and steel particles. Magnets are geometrically arranged to form a magnetic field having a nonuniform flux density (flux density is also referred to as magnetic strength) Particles [...]
spiking of ferrofluids Ferrofluids Spiking - It is a version of the Rayleigh-Taylor instability. This is an instability of an interface between two fluids of different densities which occurs when the lighter fluid is pushing the heavier fluid. Ferrofluids Spiking Redditor Specktagon has a wonderful analogy. This happens because maple syrup layer is [...]
