Geometrical frustration is an important feature in magnetism, where it stems from the relative arrangement of spins. A simple 2D example is shown in Figure 1. Three magnetic ions reside on the corners of a triangle with antiferromagnetic interactions between them; the energy is minimized when each spin is aligned opposite to neighbors. Once the first two spins align antiparallel, the third one … WebSep 3, 2024 · Ground-breaking concepts in magnetism were developed conceptually using spinel compounds. • Spinels are prototypical examples of strongly frustrated magnets. • …
