Changing the magnetic properties of ZrO

conditions

T
he aim of the present work was to study the magnetic
properties of ZrO
2
(Mn) nanocrystals prepared by the
microwave-assisted hydrothermal synthesis using KMnO
4
precursor. The structural characterization was performed by
means of X-ray diffraction. The morphology of the samples
was studied by use of STEM microscopy. The magnetic
properties were studied by means of AC susceptibility. All
the samples demonstrated the Curie-Weiss behaviour at
higher temperatures with negative values of Curie-Weiss
temperature.Itwasshownthattheconditionsofthesynthesis,
e.g. pH, can be adjusted to decrease the value of Curie-Weiss
temperature and reduce antiferromagnetic interactions
