Magnetic properties isotropic materials

We discuss in this section whether routes may be envisaged towards nanocomposite materials with magnetic properties significantly superior to present properties. The target remanent magnetisation value is estimated to be jUtMr = 1.2 T in isotropic systems and poMt = 1.5 T in anisotropic... 

Here we have assumed a homogeneous isotropic material but in general the permeability is a second-rank tensor jt having 3x3 elements. The applied magnetic field is modified by the bulk magnetic properties of the substance and thus the magnetic field inside the sample becomes... 

Platinum-cobalt and platinum-iron magnets. These alloys are isotropic corrosion resistant, ductile, and hence easy to machine. Their magnetic properties are superior to most other permanent magnet materials except that of Nd-Fe-B. Due to the expensive price of platinum, they were replaced by Nd-Fe-B. 

An Outline of Non-linear Effects in Dielectrics. Constitutive Relations in Linear Media. We shall be considering homogeneous and isotropic dielectrics, the electric, magnetic, and optical properties of which, in the absence of external fields, are described by the following three scalar quantities, characteristic of the material of which the medium consists e = electric permittivity /X = magnetic permeability n = refractive index.
