reported the strain-assisted spin transfer torque (STT) induced magnetization
switching in CoFeB-based magnetic tunnel junctions by combining phase-field method with micromagnetic simulations.
In the case of [A.sub.0] [parallel] a, the induced magnetization value decreases with decreasing irradiated photon energy.
The induced magnetizations by the c-axis-polarized photons are slightly larger than those by the a-axis-polarized ones.
While rotating in the a-b plane, the induced magnetizations disappear.
The induced magnetization
density M can be written as
Where M is the induced magnetization
of the particle, m is the mass of the particle, [chi] is the specific magnetic susceptibility, and H is the magnetic field intensity.
Generally, Q value is lower than 1 (Figure 3(d)), indicating that their magnetization is dominated by induced magnetization.
Among them, Q value of mafic rocks ranges between 2 and 6, indicating the dominance of natural remanent magnetization with respect to the induced magnetization (Table 2).
Q values of marble and gneiss are lower than 1, suggesting the dominant contribution of induced magnetization, whereas quartzite has Q values > 1, indicating a strong contribution of remanent magnetization (Table 4).
It makes a variable induced magnetization and further links to complex magnetic anomalies in ground surface.
