We argue that essentially all of the signatures of magnetism can be sorted into two distinct categories: (1) magnetic phases (e.g., ferromagnetic or Kondo) involving local magnetic moments and their coupling to itinerant electrons; (2) metamagnetic effects that are mediated by attractive electron - electron interactions that do not involve local moments.

The film also has ferromagnetic properties, in which the atoms» magnetic moments align in the same direction.

In this state, an additional antiferromagnetic order is observed in addition to superconductivity, i.e. the magnetic moments (the «elementary magnets») in the material partly point in one direction and partly in the opposite direction in a regular manner.

That means when you move in a certain direction through the material, the magnetic moments first point in one direction, become larger and then smaller and then point in the opposite direction, become bigger and then smaller again etc..

A number of questions, such as how the magnetic moments in the polymer arise and why the magnetization is less than might theoretically be expected, still need to be answered, he writes.

It's the result of a particular magnetic property of materials — the magnetic moment, a tiny magnetic field produced by electrons orbiting the nucleus of an atom.

But a strong external magnetic field can reduce that resistance by bringing the magnetic moments into alignment.

In many crystalline materials, magnetic moments are randomly oriented, which increases the electrical resistance of the material.

«When the magnetic moments of the electrons are aligned in a magnetic field, the electron cloud shape and the atomic arrangement become more symmetric and homogenous.

Bismuth ferrite is an antiferromagnetic, which means that the magnetic moments of its magnetic sublattices (structures formed by atoms with the same parallel spins) cancel each other out, and the total magnetization of the material is close to zero.

«The magnetic moments bind spin and direction tightly together, so any disturbance would need to flip the electron's spin in order to change its direction.»
