The metallic compound MnBi has high intrinsic coercivity with large positive temperature
coefficient. The coercivity of MnBi exceeds 12 kOe and 26 kOe at 300 K and 523 K …

MnBi particles are obtained from bulk MnBi using mechanochemical processing. The
structure and magnetic properties of the MnBi particles are investigated by means of X-ray …

The effect of jet milling conditions on phase decomposition, particle size and magnetic
properties of MnBi alloy were studied. It is observed that jet milling pressure plays a critical …

In conventional magnets, neodymium with added heavy rare-earths is used in order to
induce high output and size reduction. But as deposits of heavy rare-earths such as …

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 …

In this chapter, we are presenting the developments in permanent magnetic materials and
their processing techniques. We discuss different alloy systems, rare-earth (RE) Nd-Fe-B …

Low-temperature phase manganese bismuth (LTP-MnBi) was synthesized by low-
temperature liquid phase sintering in ultrahigh vacuum at 275, 325 and 375° C. The …
