What is antiferromagnetic/ferromagnetic coupling, and what is the difference between the two? I'm referring to coupling between two two-level half-flux quantum systems for example.

Antiferromagnetic coupling is a type of magnetic interaction between neighboring atoms or molecules where their magnetic moments are aligned in opposite directions. This results in a net magnetic moment of zero and no external magnetic field is observed.
Ferromagnetic coupling is a type of magnetic interaction between neighboring atoms or molecules where their magnetic moments are aligned in the same direction. This results in a net magnetic moment and can be observed with an external magnetic field.
Antiferromagnetic and ferromagnetic coupling are caused by the exchange interaction between neighboring atoms or molecules. This interaction is a result of the quantum mechanical exchange of electrons and their spin orientations.
Antiferromagnetic and ferromagnetic coupling are important in various fields such as data storage, spintronics, and magnetic sensors. They are also used in the development of magnetic materials and devices for medical imaging and energy harvesting.
Antiferromagnetic and ferromagnetic coupling can be studied using various experimental techniques such as magnetometry, neutron scattering, and electron microscopy. Theoretical methods such as density functional theory and Monte Carlo simulations can also be used to understand the underlying mechanisms of these magnetic interactions.
