Abstract Scope

To study the Manganese (Mn) effects on magnetic properties of high entropy alloys (HEAs), we prepared a single-crystal (CoCrFeNi)xMn1-x to eliminate the grain boundary effects. The samples with concentration gradients of Mn are sliced at different portions with different Mn contents. The magnetic and structural properties of (CoCrFeNi)xMn1-x are examined as a function of temperature. We found that Mn content and magnetic properties have positive correlations. Our neutron diffraction data also show the Mn effect on the diffraction profiles.
