Microstructure and isothermal magnetic entropy change of La(Fe0.89Si0.11)13 in a single-phase formation process by annealing.

Highlights: [•] The single-phase formation process of La(Fe0.89Si0.11)13 was investigated. [•] The NaZn13-type single-phase is obtained by annealing for 300h at 1323K. [•] The Curie temperature is increased by annealing due to compositional homogenization. [•] The isothermal magnetic entropy change was related to the microstructure. [•] The peak position of the isothermal magnetic entropy change is affected by annealing. [Copyright &y& Elsevier]
