Crystalline anisotropy energy
WebThe degree of thermal anisotropy affects critically key device-relevant properties of layered two-dimensional materials. Here, we systematically study the in-plane and cross-plane thermal conductivity of crystalline SnSe2 films of varying thickness (16–190 nm) and uncover a thickness-independent thermal conductivity anisotropy ratio of about ∼8.4. … WebNov 18, 2016 · Rare earth elements with high atomic numbers help to create large magneto-crystalline anisotropy as the spin-orbit-coupling constant is proportional to the atomic number 4. It is therefore a formidable task of materials science to turn soft magnetic 3 d transition metal elements like Fe and Co into hard magnetic materials.
