Provided are inverse phase allotrope rare earth (IPARE) magnets, methods of forming thereof, and applications of IPARE magnets. Unlike conventional samarium-cobalt magnets, IPARE magnets maintain their hexagonal lattice structures over a range of equiatomic compositions, such as when concentrations of different elements are within 10 atomic % of each other. An IPARE magnet may comprise cobalt, iron, copper, nickel, and samarium and a concentration of cobalt may be between 17-27 atomic %. An IPARE magnet may be substantially free from zirconium and/or titanium. An IPARE magnet may be formed by quenching a molten mixture of its components. The quenching may be performed in a magnetic field. After quenching, the IPARE magnet may be machined. Furthermore, IPARE magnets may be used as a structural element, e.g. in an electric motor.
