Kinetical analysis of the heat treatment procedure in SmCo5 and other rare-earth transition-metal sintered magnets

Microstructural changes during the slow-cooling annealing of nanocrystalline SmCo 2:17 type magnets

“…(ii) Part of the coercivity increase should be attributed to elimination of lattice defects [36][37][38] like vacancies or Sm-excess atoms from the 2:17 nanocells [36]. This is the ''perfect lattice hypothesis'' [36][37][38]. (iii) Expulsion of copper from the 2:17 cells.…”

Modeling hysteresis curves of anisotropic SmCoFeCuZr magnets

“…This is a very unrealistic assumption, since there are many lattice defects in the crystalline structure, as for example vacancies and substitutional atoms in solid solution. In many cases, lattice defects are so important that they directly determine the coercive force [30,[32][33][34][35].…”

Impurity phases in Sm(CoFeCuZr)z magnets: The role of Zr

“…More specifically, it has been confirmed by several authors [13,14] that the angu- [2]. The coercivity increase in the slow cooling anneal may also be associated with elimination of lattice defects [15]. An overview of hightemperature 2:17 magnets has recently [1] discussed some of these issues.…”
