Spinellen

Spinellen is a hypothetical crystalline material discussed in theoretical and speculative literature on spintronics and two-dimensional magnetism. In these accounts, Spinellen is described as a layered ferrimagnetic semiconductor with a tunable bandgap and high spin polarization, properties that are considered favorable for spin-based information processing and nonvolatile memory.

The proposed structure comprises alternating magnetic and nonmagnetic layers arranged in a hexagonal or tetragonal lattice, enabling exfoliation into two-dimensional sheets that retain long-range magnetic order at or above room temperature. The material is described as having strong spin-orbit coupling, anisotropic magnetic interactions, and what is termed a favorable magnetic damping profile, yielding potential for fast switching and low power operation.

Synthesis discussions in the literature typically point to chemical vapor deposition and molecular beam epitaxy as plausible routes, with ongoing debates about stoichiometry, defects, and stability. As Spinellen is currently hypothetical, no confirmed experimental realization has been reported, and reported properties remain theoretical predictions.

Potential applications include spin-based memory and logic devices, magneto-optical modulators, and quantum information components that rely on spin coherence. Challenges cited include achieving robust magnetic ordering at ambient conditions, scalable production of high-quality crystalline or exfoliated sheets, and integration with existing semiconductor platforms.

The term Spinellen combines the element of spin with a suffix drawn from conventional material-naming practice. See also spintronics, two-dimensional magnets, ferrimagnet, and magneto-optics.
