ferromagnet

The magnetization at any point in a ferromagnet can only change by rotation.

The added energy term implies a shift in the switching field of the ferromagnet.

If the ferromagnet is large enough, its magnetization can divide into domains.

Unlike a ferromagnet, a diamagnet is not a permanent magnet.

In an Ising ferromagnet below this does not happen.

Thus electrons with a larger chemical potential will accumulate at the boundary of the ferromagnet.

One way to remove the magnetic poles inside a ferromagnet is to make the magnetization uniform.

Below this temperature the ferromagnet has a spontaneous magnetization.

To illustrate the structure, consider a ferromagnet which is composed of atoms each equipped with a tiny magnet.

When these magnets are lined up, the inside of the ferromagnet bears a strong analogy to the way empty space can be structured.

He instead looked for the opposite effect, that is, that spinning a ferromagnet could change its magnetization.

In that case the Curie-point is seen as a phase transition between a ferromagnet and a 'paramagnet'.

A ferromagnet, like a paramagnetic substance, has unpaired electrons.

A ferrimagnetic material is similar to a ferromagnet but has two different types of atoms with opposing magnetic moments.

A phase transition from a ferromagnet to a paramagnet is continuous and is of second order.

Note that since this is spinning, this is not a non-moving ferromagnet.

Furthermore, the resonant absorption of microwave energy causes local heating of the ferromagnet.

The essential physics underlying the phenomenon is the exchange interaction between the antiferromagnet and ferromagnet at their interface.

As an example of what an approximate symmetry means, suppose we lived inside an infinite ferromagnet, with magnetization in some particular direction.

When an external magnetic field is applied to a ferromagnet such as iron, the atomic dipoles align themselves with it.

She is best known for her work on a variety of superconductors, magnetic materials, and superconductor/ferromagnet heterostructures.

If the insulating layer is thin enough (typically a few nanometers), electrons can tunnel from one ferromagnet into the other.

The classic ferromagnet is iron.

His explanation of spontaneous symmetry breaking in terms of a little man living inside a ferromagnet has often been cited by later popularizers.

As size of a ferromagnet increases, the single-domain state incurs an increasing energy cost because of the demagnetizing field.
