Spintilt

Spintilt is a term used in condensed matter physics to describe a phenomenon where the spins of electrons in a material are no longer perfectly aligned in a particular direction, but rather have a component tilted away from that direction. This tilting can arise from various mechanisms, including interactions with other particles, external magnetic fields, or crystal lattice imperfections.

One common cause of spintilt is the presence of magnetic impurities or defects within a non-magnetic host material. These imperfections can create local magnetic moments that interact with the spins of the host electrons, leading to a slight deviation from their expected orientation. Another mechanism is the spin-orbit interaction, a relativistic effect that couples an electron's spin to its orbital motion. This interaction can be particularly strong in materials containing heavy elements, and can induce spintilt even in the absence of external magnetic fields.

Spintilt can have significant consequences for the electronic and magnetic properties of materials. For example, it can affect the conductivity, magnetization, and spin transport characteristics. Understanding and controlling spintilt is crucial for the development of advanced spintronic devices, which aim to utilize the electron's spin in addition to its charge for information processing and storage. Research in this area explores methods to induce, manipulate, and detect spintilt in various materials, paving the way for novel technological applications.
