dc.description.abstract | Structural, electrical, magnetic, and specific heat measurements were carried out on
ZnCr2Se4 single crystal and on nanocrystals obtained from the milling of this single crystal after 1, 3,
and 5 h, whose crystallite sizes were 25.2, 2.5, and 2 nm, respectively. For this purpose, the high-energy
ball-milling method was used. The above studies showed that all samples have a spinel structure, and
are p-type semiconductors with less milling time and n-type with a higher one. In turn, the decrease
in crystallite size caused a change in the magnetic order, from antiferromagnetic for bulk material and
nanocrystals after 1 and 3 h of milling to spin-glass with the freezing temperature Tf = 20 K for the
sample after 5 h of milling. The spin-glass behavior for this sample was derived from a broad peak of
dc magnetic susceptibility, a splitting of the zero-field-cooling and field-cooling susceptibilities, and
from the shift of Tf towards the higher frequency of the ac susceptibility curves. A spectacular result
for this sample is also the lack of a peak on the specific heat curve, suggesting a disappearance of the
structural transition that is observed for the bulk single crystal. | pl_PL |
