The constant drive to replace rare-earth metal magnets has initiated great interest in an
alternative. Manganese (Mn) has emerged to be a potential candidate as a key element in …

Recent advances in rare-earth-free hard-magnetic materials including magnetic bulk, thin
films, nanocomposites and nanostructures are introduced. Since the costs of the rare-earth …

A method has been developed for manufacturing rare-earth-free MnBi-based magnets
capable of filling the existing “gap” between the ferrite and rare-earth permanent magnets …

We report magnetic properties and microstructure of high energy-product MnBi bulk
magnets fabricated by low-temperature ball-milling and warm compaction technique. A …

This study investigated the evolution of magnetic properties in low-temperature vacuum-
sintered MnBi samples over an 18-month period at room temperature. Two sample …

MnBi low-temperature phase (LTP) powders with composition of Mn 50 Bi 50 were prepared
using traditional casting followed by annealing and subsequent low energy ball milling with …

The low-temperature phase (LTP) of the binary MnBi alloy system is well recognized for its
potential to yield the highest maximum energy product value among the rare earth element …

Since the solidification of MnBi alloys is peritectic, their microstructures always consist of the
starting phases of Mn and Bi and the productive phase MnBi. The high performance of MnBi …

MnBi alloys were fabricated by arc melting and annealing at 573 K. The heat treatment
enhanced the content of the low-temperature phase (LTP) of MnBi up to 83 wt%. The Bi …

The intermetallic compound LiMnBi was synthesized by the two-step solid-state reaction
from the elements. A synthesis temperature of 850 K was selected based on in situ high …
