«The Effect of Thermal Motion of the Domain Wall on the Thermodynamic Properties of the Cylindrical Iron Nanowire »
0807–0821 (2021)

PACS numbers: 65.40.gd, 75.30.Sg, 75.40.Cx, 75.60.Ch, 75.60.Ej, 75.75.Fk, 81.07.Gf

The effect of the thermal motion of a domain wall (DW) on both the entropy and the heat capacity of the electron, magnon and phonon (Debye component) subsystems of cylindrical iron nanowire is investigated. As found out, the entropy and the heat capacity caused by the DW dynamics can be of the same order of magnitude with the corresponding thermodynamic characteristics of above-mentioned subsystems. The critical parameters (nanowire diameter, temperature) for such a circumstance are determined. The method of the critical nanowire diameter increase by means of the decrease of nanowire magnetization is proposed. As ascertained, the iron-nanowire diameter value, at which the transition from the longitudinal DW to the domain wall in the form of a Bloch point occurs, is equal to 38 nm.

Key words: iron nanowire, magnetization, domain wall, heat capacity, entropy
