Temperature-dependent multi-k magnetic structure in multiferroic Co3TeO6
S. A. Ivanov, R. Tellgren, C. Ritter +6
A complex magnetic order of the multiferroic compound Co3TeO6 has been revealed by neutron powder diffraction studies on ceramics and crushed single crystals. The compound adopts a…
Ferrimagnetism, Antiferromagnetism and Magnetic Frustration in LaSrCuRuO (0 <= x <= 1)
P. Anil Kumar, R. Mathieu, R. Vijayaraghavan +6
We studied structural and magnetic properties of a series of insulating double perovskite compounds, LaSrCuRuO (0 x 1), representing doping via \tex…
Short-range spin order and frustrated magnetism in Mn2InSbO6 and Mn2ScSbO6
S. A. Ivanov, P. Nordblad, R. Mathieu +3
The complex metal oxides Mn2ASbO6 (A=In, Sc) with a corundum-related structure A3BO6 have been prepared as polycrystalline powders by a solid state reaction route. The crystal stru…
Magnetic order near 270 K in mineral and synthetic MnFeSbO ilmenite
R. Mathieu, S. A. Ivanov, G. V. Bazuev +4
The structural and magnetic properties of MnFeSbO single-crystalline mineral and ceramic samples synthesized under thermobaric treatment have been investigated, and compare…
Formation process and superparamagnetic properties of (Mn,Ga)As nanocrystals in GaAs fabricated by annealing of (Ga,Mn)As layers with low Mn content
Janusz Sadowski, Jaroslaw Z. Domagala, Roland Mathieu +4
X-ray diffraction, transmission electron microscopy, and magnetization measurements are employed to study the structural and magnetic properties of Mn-rich (Mn,Ga)As nanocrystals e…
Voids and Mn-rich inclusions in a (Ga,Mn)As ferromagnetic semiconductor investigated by transmission electron microscopy
A. Kovacs, J. Sadowski, T. Kasama +5
Voids adjacent to both cubic (ZnS-type) and hexagonal (NiAs-type) Mn-rich nanocrystals are characterized using aberration-corrected transmission electron microscopy in annealed Ga0…
