Determination of domain wall energy and critical single-domain particle size based on domain structure observations of ThMn12-type magnetic particles

•Domain width and grain size of selected ThMn12 structure compounds were measured.•Well characterized Sm2Fe17N3 particles were used as standard for measurements.•Domain wall energy (γ) and single-domain grain critical size (Rc) were calculated.•Classical equations for domain structure analyses were...
