Approximate Equation for Energy Barrier in Magnetic Recording
نویسندگان
چکیده
We derive an approximate energy barrier equation considering its adaptation to our model calculation employing the Néel-Arrhenius with Stoner-Wohlfarth grain or dot in magnetic recording. First, we calculate as a function of field by numerical for angle 0 180 deg between easy axis and field. This relation is represented 90 deg, taking account Pfeiffer’s approximation deg. Next, shape anisotropy cuboid cylinder also equation, since energy.

متن کاملAn approximate analytical solution of the Bethe equation for charged particles in the range of radiotherapy energy
Charged particles such as protons and carbon ions are an increasing tool in radiation therapy. However, unresolved physical problems prevent optimal performance, including estimating the deposited dose in non-homogeneous tissue, is an essential aspect of optimizing treatment. The Monte Carlo (MC) method can be used to estimate the amount of radiation, but, this powerful computing operation is v...
