Researchers have created a cutting-edge structure by placing a very thin layer of a special insulating material between two magnetic layers. This new combination acts as a quantum anomalous Hall ...
Ferrite ceramics and ferromagnetic materials are a number of crystalline materials that exhibit ferromagnetism (or ferrimagnetism). Ferromagnetism is a phenomenon by which a material can exhibit a ...
When iron is cooled through 770 °C, a phase transition occurs and the metal becomes ferromagnetic. The microscopic origins of magnetism are electron spins and orbital currents. Running this ...
Combining nanostructured magnetic media with nanoplasmonic antennas has propelled commercially viable data-storage densities beyond one terabit per square inch. Figure 1: Areal density (on a log ...
Plus Cobalt Monolayers Now, however, a Spanish-German team has shown that these effects are significantly enhanced when a few monolayers of the ferromagnetic element cobalt are inserted between ...
