Abstract

The high entropy (FeCoNiP)100-XWX coatings synthesized by chemical deposition have been investigated. Depending on the tungsten content, the coatings are a bcc solid solution or an amorphous alloy, or contain both phases simultaneously. From the analysis of the approach of magnetization to saturation by the correlation magnetometry method, it was found that the dimensionality of magnetization exchange
correlations changes with a change in the tungsten concentration. At X > 10, three-dimensional exchange correlations of magnetization are realized, at 3 ≤Х ≤ 9 – two-dimensional exchange correlations, and at
X < 3 – one-dimensional exchange correlations of magnetization. These observations can be attributed to the two-phase structure of the coating, along with the flattened shape of regions where the local easy
magnetization axis remains uniform.
