A canted antiferromagnet is a type of antiferromagnetic material in which the magnetic moments of the atoms are arranged in an antiparallel manner, but are also tilted or canted with respect to each other. This results in a net magnetization, which is perpendicular to the antiferromagnetic ordering.
In a regular antiferromagnet, the magnetic moments of the atoms cancel out each other, resulting in no net magnetization. However, in a canted antiferromagnet, the magnetic moments are not perfectly antiparallel, but are slightly tilted with respect to each other. This creates a small net magnetization, which is perpendicular to the antiferromagnetic ordering.
Canted antiferromagnets are important in the study of magnetic materials, as they can exhibit interesting and useful magnetic properties. For example, they can be used in magnetic data storage devices, where the small net magnetization can be used to encode information. They can also exhibit magneto-optical effects, where the interaction of light with the magnetic field can result in changes in the optical properties of the material.
Examples of canted antiferromagnets include chromium dioxide (CrO2), nickel oxide (NiO), and manganese oxide (MnO).
