Q: Its existence was first confirmed by neutron diffraction experiments conducted by Clifford Shull on a sample of manganese oxide. In a sample exhibiting this characteristic, the magnetic moments align in a regular pattern with neighboring moments pointing in opposite directions, resulting in a net magnetization of zero. At certain temperatures, these materials become disordered and begin to exhibit paramagnetic properties, a point which is known as the Nel point, and which is similar to the Curie point. FTP, identify this type of magnetism which is the opposite of ferromagnetism.
