Abstract

Microstructure and magnetic properties of Mn-X-N (X: Ni, Zr, and B) alloy system were investigated in this study. The samples showed low remanence; however, relatively high coercivities of 0.5-4.4 kOe (40-350 kA/m) were obtained in the Mn-Ni-N system. Scanning electron microscopy-energy dispersive X-ray spectrometry (SEM-EDX) and transmission electron microscopy-energy dispersive X-ray spectrometry (TEM-EDX) analyses revealed that the Mn-Ni-N sample with high coercivity consists of a lamellar structure with the spacing of 0.5-2 μm. It is also found that the lamellar structure is composed of two phases with composition of 97.4 at% Mn-2.6 at% Ni and 86.7 at% Mn-13.3 at% Ni.
