Abstract We describe the procedure to obtain composites made of a nickeliron alloy and magnetite. A KOH concentration of 14 mol/liter is required. Metal diffraction lines are broad, due to heterogeneous composition and bad crystallization. Balls of metal μm wide stuck to magnetite octahedra are easily observed by SEM and TEM.

Oct 27, 2015· Permanent magnets. The most common metals used for permanent magnets are iron, nickel, cobalt and some alloys of rare earth metals. There are two types of permanent magnets: those from "hard" magnetic materials and those from "soft" magnetic materials. "Hard" magnetic metals tend to stay magnetized over a long period.

Iron, the most ubiquitous of the transition metals and the fourth most plentiful element in the Earth's crust, is the structural backbone of our modern infrastructure. It is therefore ironic that as a nanoparticle, iron has been somewhat neglected in favor of its own oxides, as well as other metals such as cobalt, nickel, gold, and platinum.
