Anisotropic magnets demonstrate varying magnetic properties along different crystalline directions. They find varying applications in high density magnetic storage media, magneto-optical recording, and power generation. Materials containing elements with strong spin-orbit coupling, and large orbital moment are found to be strongly anisotropic.
Traditionally strong magnets consist of rare-earth elements. Due to their low availability, there is a search for magnetic materials containing transition metals. One such candidate is Fe0.25TaS2. We use first-principles density functional calculations to study its magnetic properties.
