Latest Ferromagnetism Stories
For purposes of their research, the scientists irradiated two separate layered systems with ultrashort laser pulses on the order of just one hundred femtoseconds (10-15 s).
Thanks to new nanotechnology tools and the tenacity of star physics students, researchs have cracked the code to a magnetic mystery known as Barkhausen noise that scientists have been trying to solve for over 100 years.
While experts had previously only confirmed the existence of two states of magnetism, experts from the Massachusetts Institute of Technology (MIT) report that they have been able to experimentally demonstrate the existence of a third kind.
Geologic evidence shows the Earth's magnetic field flips about once every 450,000 years. The last reversal happened about 780,000 years ago, so looking at the average interval, we are overdue.
Spintronic technology, in which data is processed on the basis of electron “spin” rather than charge, promises to revolutionize the computing industry with smaller, faster and more energy efficient data storage and processing.
Berkeley Lab Researchers Take a Mesocale Look at Magnetic Vortex Formations
As scientists learn to manipulate little-understood nanoscale materials, they are laying the foundation for a future of more compact, efficient, and innovative devices.
Scientists have taken an important step forward in developing a new material using nano-sized magnets that could ultimately lead to new types of electronic devices, with greater processing capacity than is currently feasible.
An international team of researchers from Germany and the Netherlands has developed a new material for storage media.
In close collaboration with colleagues from Bochum and the Netherlands, researchers from the Helmholtz-Zentrum Berlin (HZB) have developed a novel, extremely-thin structure made of various magnetic materials.
An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
