Abstract
In this study, Fe and Co tablet samples, which show ferromagnetic properties at room
temperature, were magnetised for 300 seconds in a 1T (10 kG) of size magnetic field, which had
12.94 mm distance between its poles. The magnetic field applied on the ferromagnetic samples were
measured as F. W. Bell Gauss/Teslameter (Model 5080) and 1 tesla (10 kG) when the distance
between its poles were 12.94 mm. Then, the change emerged in the σ Kα and σ Kβ cross sections of
Fe and Co were respectively measured as 20º, 40º, 60º, 80º, 100º, 120º and 140º release angles in
order. The samples were alerted with KX-rays of silver alerted from Cd-109 radioisotope source of
40 mCi.
During the study, an HPGe detector, which has the beryllium window with 25µm diameter and with
(FWHM) 210 eV full width at half maximum in 5.9 keV was used. The crystal thickness of this
detector was 10 mm and its active field was 200 mm2
, the voltage to be used on the detector was
applied till -1500 V at maximum and the shaping time were set as 10µs. The liquid, which is located
in a crystal counter and FET were hold in a 30 liters of a liquid nitrogen container (dewar) was kept
under nitrogen boiling temperature.
The results showed that specifically the magnetization of Fe increased its KX-ray fluorescence cross
sections and the fluorescence cross sections of KX-ray fluorescence cross sections for Fe without
magnetization were anisotropic although it was not encountered with any anisotropy of magnetized
Fe X-rays. Consequently, this was an expected situation as the magnetised Fe and the anisotropy of Co in the σ Kα and σ Kβ values were orientations of ions generated after alerted with photon, which
was the anisotropy source of X-rays. However, to make the results more useful, it is necessary to
make more studies that are experimental and support these results with studies determining the
orientations of atoms in magnetized samples.
