Ms = ∣M(r)∣ is the saturation magnetization, \({{{\mathcal{A}}}\) is the exchange-stiffness constant, \({{{\mathcal{D}}}\) is the constant of isotropic bulk DMI, and μ0 is the vacuum permeability (μ0 ≈ 1.256 × 10−6 N A−2). The notation \(| ...
The units of B and H in SI unit system are T and A/m, respectively. Magnetic field intensity inside an object with magnetization M is B = μ0(M + H). Substitution of expression for M makes B = μH, where μ = μ0(1 +χ) is the magnetic permeability of matter. The entire ...
At outcrops, serpentinite carbonation is controlled by structural permeability and concentrated along the basal contact of the ophiolite with the underlying sediments and along faults within the serpentinite. Soapstone alteration zones reach several hundred meters into the ophiolite, while fracture-related ...
where l is the length of the solenoid, µo is the permeability of free space,*and the subscript E reminds us that the interior of the solenoid is empty. Multiplying and dividing the right-hand side of Eq 36.4 by the cross-sectional area A, we can rewrite Eq. 36.4 in terms of the...
In this invention, “weakly-magnetic material” in a multi-axis magnetic lens means that permeability of the material is much smaller than that of the upper and lower magnetic conductor plates thereof. In this invention, “magnetic-circuit gap” in a magnetic lens or sub-lens means that the ...
