Dislocations in manganese-doped InSb

A microstructural study of a quenched InSb ingot

“…The mictomagnetism found in InSb〈Mn〉 was interpreted in terms of a doped dislocation in the form of a core from the magnetic materials Mn 2 Sb and MnSb surrounded by a shell of In 1 -x Mn x Sb solid solu tions [2].…”

“…As a result, a new ferromag netic semiconductor with a Curie temperature T C = 320 K was obtained [3][4][5].…”

Microstructure of quenched doped InSb

“…One distinction between undoped and doped InSb is that, in the latter case, dislocations contain impurity atoms. For example, elemental microanaly sis data [6] demonstrate that, in quenched InSb〈Mn〉 samples, most of the manganese goes to the doping of dislocations in the semiconductor lattice, whereas the [14]; (b) dislocation outcrops on the surface of a quenched sample; (c) elemental con centration profiles across dislocation outcrops [6].…”

“…A model was pro posed for a doped dislocation in the form of a core from ferrimagnetic Mn 2 Sb and ferromagnetic MnSb clusters surrounded by a shell of In 1 -x Mn x Sb solid solutions [6].…”

“…As a result, a new soft magnetic ferromag netic semiconductor with a Curie temperature Т C = 320 K was obtained [7][8][9].…”
