WebSep 7, 2024 · Anisotropy is the property of being directionally dependent. Magnetocrystalline anisotropy refers to a crystal's property to be more easily magnetized in some directions in comparison to others. For a crystal, the axis easiest to magnetize is known as the easy axis, and the axis hardest to magnetize is known as the hard axis. WebThe degree of thermal anisotropy affects critically key device-relevant properties of layered two-dimensional materials.
