Designing shape anisotropic SmCo5 particles by chemical synthesis to reveal the morphological evolution mechanism.

In this work, we describe a new protocol to synthesize SmCo5 single crystal particles with remarkable shape anisotropy (hexagonal and rodlike), which exhibit a giant coercivity of 36.6 kOe and a high Mr/Ms value of 0.95 after an alignment. On this basis, the morphological evolution mechanism is illustrated by employing the template effect.
