INTRODUCTION The use of antiferromagnetic materials for spintronic applications has recently been identi ed as one of the most promising paths for future technology development [1{4]. Antiferromagnetic Materials. In an antiferromagnet, unlike a ferromagnet, there is a tendency for the intrinsic magnetic moments of neighboring valence electrons to point in opposite directions. The applications of a ferromagnetic substance are comprehensive. In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions.

Antiferromagnetic materials In nature, antiferromagnetic order is ubiquitous compared to ferromagnetic order. In what class does one typically learn that atoms emit EM radiation? In antiferromagnetic materials such as chromium, below the Neel temperature of 37 °C, under the applied magnetic field the neighboring atomic moments are antiparallel to each other, which leads to a zero net magnetization; therefore, such kind of materials are insensitive to a magnetic field. Antiferromagnetic structures were first shown through neutron diffraction of transition metal oxides such as nickel, iron, and manganese oxides. When the two magnetization vectors of the ferromagnetic layers are aligned, the electrical resistance will be lower (so a higher current flows at constant voltage) than if the ferromagnetic layers are anti-aligned.
