Quantum Theory of Magnetism
Ferrimagnet, below a critical temperature, has resultant spontaneous
magnetization and therefore is like a ferromagnet. On the other hand, for high
temperatures, the susceptibility shows a Curie–Weiss behaviour with a negative
paramagnetic ...

Resonant Magnon-Phonon Polaritons in a
Ferrimagnet
The influence of a dynamic magnetoelectric interaction on TE and TM polaritons in a ferrimagnet in IR region of the spectrum has been considered. Frequency dispersions of dielectric and magnetic tensors were taken into account.

Molecular Magnetism: From Molecular Assemblies to the Devices
Above the temperature of magnetic ordering, Tc, a ferrimagnet becomes a
paramagnet that obeys the Curie-Weiss law. In the simplest case of a two
sublattice ferrimagnet whose respective magnetic moments, and Mg, are align
antiparallel to ...

Modern Physical Organic Chemistry
An interesting case is the ferrimagnet. A ferrimagnet contains two different types
of spin centers that have different local magnetic moments (for definitions of spin
states, see Chapter 14). For example, one could be spin /i (a radical) and one ...

A self-consistent formulation of the exchange energy density, effective exchange field, and Poynting vector is carried out, for a general ferrimagnet, in terms of the spin and orbital angular momentum densities.

Physics of Ferromagnetism 2e
Therefore spinflopping can be observed in a relatively weak field near the
compensation point. Figure 19.11 is a conceptual spin phase diagram of an N-
type ferrimagnet. The critical fields, H01 and Hcz, go to zero at the compensation
point.
