Abstract
Abstract We have designed and prepared heterostructured (SmCo7/FeCo)/SmCo5 multicomponent magnets by high-pressure thermal compression. The coordination and interaction behavior of SmCo7/FeCo and SmCo5 phase regions during high-pressure thermal compression and magnetic reversal process were studied. The introduction of SmCo5 can improve the coercivity of the magnet. The heterostructured (SmCo7/FeCo)/SmCo5 magnet with 30 wt% SmCo5 content shows optimal magnetic properties with Mr of 10.3 kG, Hci of 6.0 kOe, and (BH)max of 16.7 MG Oe.
