Magnetic anisotropy is often tuned through various approaches, including chemical substitution, shape engineering, defect manipulation, and strain. Here, we demonstrate the strain-mediated control of magnetic anisotropy in room-temperature ferromagnetic CaFeMoO. In particular, the anisotropy constant () is tuned fromkJ m(in-plane) to 180 kJ m(out-of-plane) via substrate-driven tensile strain (0.9%) in thin films. We argue that the negative value of magnetostriction promotes out-of-plane anisotropy through magnetoelastic coupling (MEC) in CaFeMoOfilms. In addition, the experimental results are well supported by micromagnetic simulations. Our results show that even modest tensile strain is sufficient to induce easy-axis reorientation in double perovskite CaFeMoOthrough strong MEC.

Diamagnetism
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets.

Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
