We present a comprehensive study of Ho(Ni0.2Co0.2Fe0.2Mn0.2Cr0.2)O3 high-entropy oxide perovskite thin films. Aside from growth, structural, chemical, and macroscopic magnetic characterization, we performed element-specific, temperature-dependent X-ray absorption spectroscopy (XAS) using X-ray magnetic circular dichroism (XMCD) and X-ray magnetic linear dichroism (XMLD) at all relevant absorption edges. The results indicate predominant ferrimagnetic order with a transition temperature below 150 K and the formation of antiferromagnetic clusters below 50 K.
