antiferromagnetic material

antiferromagnetic material

An "antiferromagnetic material" consists of atoms having magnetic moments but the neighbouring magnetic moments are aligned anti-parallel to each other, thus the net magnetic moment of the material is 0 (zero). The material is magnetized in the direction of a magnetic field like a paramagnetic material when placed in a weak magnetic field. When the magnetic field is increased, it is strongly magnetized in the direction of the magnetic field like a ferromagnetic material. It exhibits a double-hysteresis loop against changes of the magnetic field.
