Magnetostriction has following applications: this effect is used in high frequency oscillators and generators of super sound. For under water projectors and sound detectors Reference:
Magnetostriction is a reversible effect because change in magnetsation can be produced by applying stress on the material. This effect is called Villari effect. Reference:
When a ferromagnetic material is magnetised, its length either expands or contracts in the direction of the magnetisation. This effect is called magnetostriction or Joule
As the temperature of the ferromagnetic material is raised, the thermal energy of the atoms increases. At very high temperature, the thermal energy is sufficient
To explain the phenomenon of ferromagnetism, Weiss proposed a hypothetical concept of ferromagnetic domains. He postulated that the neighboring atoms of the ferromagnetic materials, due
Domain is a region in a ferromagnetic material where all the magnetic dipole moments are aligned. The domains are of microscopic size of the order
The susceptibility of antiferromagnetic materials are small and positive. It increases with the rise in temperature. The susceptibility becomes maximum at Neel temperature and decreases
The magnetisation of antiferromagnetic materials depends on temperature. The magnetisation increases with the rise in temperature and becomes maximum at a particular temperature. Above this
In the presence of the strong magnetic field, antiferromagnetic materials are weakly magnetised in the direction the field. This property of the materials is called
