Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Ab‐initio calculations have been used to investigate the phase stability and magnetic state of Cr_{<italic>n+</italic> 1}GaC<italic>_n</italic> MAX phase. Cr₂GaC (<italic>n</italic> = 1) was predicted to be stable, with a ground state corresponding to an antiferromagnetic spin configuration. Thin‐film synthesis by magnetron sputtering from elemental targets, including liquid Ga, shows the formation of Cr₂GaC, previously only attained from bulk synthesis methods. The films were deposited at 650 °C on MgO(111) substrates. X‐ray diffraction and high‐resolution transmission electron microscopy show epitaxial growth of (000ℓ) MAX phase.
