The first-generation rare earth permanent magnet SmCo 5 was first reported in 1967 and is a binary intermetallic compound. It consists of a RE-Co permanent magnet composed of RE atoms and other metal atoms in a ratio of 1:5. The melting point of SmCo 5 is 1350 °C and it can be defined as single or multiphase.
Rare-earth magnets: properties, processing and applications
The emergence of rare-earth magnets resulted in a step-change in the performance that could be achieved with electrical machines equipped with permanent magnets, particularly in terms of power density. For a true like-for-like comparison, there is little contention that machines with rare-earth permanent magnets offer the highest …

1 Introduction. One of the most important and wide range of applications for rare earth (REs) containing materials is the production of permanent magnets.
Rare Earth Magnets – The Ultimate Guide
Rare earth magnet properties define the core aspects that describe a magnet's strength. These properties include: Coercivity. The tendency of a magnet to resist demagnetization defines its coercivity. It defines a rare earth magnet's ability to maintain its magnetic field strength when subjected to demagnetizing factors.

Everything You Need to Know About Rare Earth Magnets
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets. A permanent rare earth magnet is one made from a material that stays magnetized.
