What is … Magnetism has been a major topic of research for centuries. MCQ Questions for Class 12 Chemistry with Answers were prepared based on the latest exam pattern. Two-dimensional (2D) ferromagnetic (FM) semiconductors with a direct electronic band gap have recently drawn much attention due to their promising potential for spintronic and magneto-optical applications. Specifically, we demonstrate that either intrinsic defects or the adsorption of molecules enhances ferromagnetic interactions. For example, MnO. Whereas in case of Antiferromagnetism domains are oppositely oriented thereby cancel out each other's magnetic moment. Magnetic moment is given by. Magnetic moments of the domains in the substance are aligned in parallel and anti-parallel directions in unequal numbers. However, the Curie temperature (TC) of recently synthesized 2D FM semiconductors is too low (∼45 K) and 2020 Nanoscale HOT Article Collection What is the formula of a compound in which the element Y forms ccp lattice and atoms of X occupy l/3rd of tetrahedral voids?
