(a) XRD pattern of as-synthesized SmCo5@Co magnets. The black lines are the standard diffraction pattern of SmCo5 (JCPDS No. 27-1122) and the green lines are the standard diffraction pattern of Co (JCPDS No. 15-0806).(b) TEM image of as-synthesized SmCo5@Co magnets. (c) TEM image of an isolated SmCo5@Co particle. (d) HRTEM image of the exterior part of SmCo5@Co particle. (e) HRTEM image of an arbitrary interior part of the particle. (f) SAED pattern of the SmCo5@Co particle shown in c).
