Latest Ferromagnetism Stories
Dilute magnetic semiconductors (DMS) have recently been a major focus of magnetic semiconductor research.
In many ionic materials, including the oxides, surfaces created along specific directions can become electrically charged.
A magnetic force microscope (MFM) can determine the distribution of stray fields at a level of tens of nanometers near the surface of magnetic films, and therefore is an effective tool for observing the domain structures in magnetic grains of submicrometer size.
A new material with a low-temperature nonmagnetic phase and a strongly magnetic high-temperature phase could potentially be used to help generate power
Scientists at the University of Massachusetts Amherst report that for the first time they have designed a much simpler method of preparing ordered magnetic materials than ever before, by coupling magnetic properties to nanostructure formation at low temperatures.
Bochum's physicists led by Prof. Dr. Hartmut Zabel have demonstrated the spin pumping effect in magnetic layers for the first time experimentally.
Neutron scattering studies of "cobalt blue," a compound prized by artists for its lustrous blue hue, are revealing unique magnetic characteristics that could answer questions about mysterious properties in other materials.
An international team of researchers from France and Germany has developed a new material which is the first to react magnetically to electrical fields at room temperature.
HZB scientists observe how a material at room temperature exhibits a unique property.
Computer files that allow us to watch videos, store pictures, and edit all kinds of media formats are nothing else but streams of "0" and "1" digital data, that is, bits and bytes.
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...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
