Magnetic Ordering - an overview ScienceDirect Topics

Both chemical and magnetic ordering are accompanied by distortion of the crystal. For example, when an alloy of Fe and Pt of equiatomic composition is cooled down from a high-temperature solid-solution, a chemical ordering begins to occur in the fcc structure at 1280 °C to form the layer-by-layer arrangement shown in Figure 24, the L1 0 structure. As this structure is of tetragonal symmetry ...

Three models of magnetic ordering in typical magnetic ...

2018-10-15  In this work, we review three models of magnetic ordering in typical magnetic materials that have been proposed based on atomic physics. The first model we discuss is the O 2p itinerant electron model for magnetic oxides, which is called the IEO model. Using this model, the magnetic structures of spinel ferrites M Fe 2 O 4, where M = Ti, Cr, Mn, Fe, Co, Ni, or Cu, and perovskite manganites La ...

The Renaissance of Magnetoelectric Multiferroics -

The electric field E, magnetic field H, and stress σcontrol the electric polarization P, magnetization M, and strain ϵ, respectively.In a ferroic material,P,M, or ϵare spontaneously formed to produce ferromagnetism, ferroelectricity, or ferroelasticity, respectively.In a multiferroic, the coexistence of at least two ferroic forms of ordering leads to additional interactions.
