Abstract. In alignment with the increasing demand for larger storage capacity and longer data retention, the electrical control of magnetic anisotropy has been a research focus in the realm of spintronics. Typically, magnetic anisotropy is determined by grain dimensionality, which is set during the fabrication of magnetic thin films.
This fact is easy to understand physically for the simplest case of a stationary 1D potential: U = U = U(x) U ( x). The absence of the y y - and z z -dependence of the potential energy U U may be interpreted as a potential well that is flat in two directions, y y and z z. Repeating the arguments of the previous section for this case, we see ...

If the temperature is kept high, the atoms would get enough kinetic energy to acquire their suitable position of minimum energy, and hence the crystal formation would be uniform. On the other hand, if the temperature is kept to be low, the atoms will not get enough kinetic energy to acquire the most energetically favorable site, …

Dimensionality reduction is a method for representing a given dataset using a lower number of features (i.e. dimensions) while still capturing the original data''s meaningful properties. 1 This amounts to removing irrelevant or redundant features, or simply noisy data, to create a model with a lower number of variables. Dimensionality reduction …
