Título: | Spin disorder scattering in magnetic metallic alloys |
Autor: | Stankiewicz, Jolanta CSIC ORCID ; Bartolomé, Juan CSIC ORCID; Fruchart, Daniel | Fecha de publicación: | 2002 | Editor: | American Physical Society | Citación: | Physical Review Letters 89(10): 106602 (2002) | Resumen: | Anomalous behavior of the resistivity at or just below the Néel temperature in antiferromagnetic metals is usually attributed to the formation of superzone gaps. However, we find that RMn12−xFex alloys which have no such gaps exhibit a similarly anomalous resistivity. We show that electron scattering by substitutional spin disorder can account for such behavior of itinerant magnets. This mechanism, which has not been studied before, leads to a relaxation rate that is proportional to x(12−x)m2, where m is the staggered magnetization. Together with spin fluctuations, phonon, and impurity scattering, it accounts well for the resistivity data we obtain for HoMn12−xFex, for 0≤x≤9, in the temperature range of 4 to 400 K. | Versión del editor: | https://doi.org/10.1103/PhysRevLett.89.106602 | URI: | http://hdl.handle.net/10261/256538 | DOI: | 10.1103/PhysRevLett.89.106602 | ISSN: | 0031-9007 |
