In this work, the effects of bis (2-methoxy-4-allylphenyl) oxalate (I) on levitation (Fz) and lateral forces (Fx) of bulk
MgB2 superconductor has been investigated and reported for the first time. All samples were prepared from magnesium powder
(Mg, 99.8 %), amorphous boron powder (B, 98 %), and bis oxalate (C22H22O6) powder by using “Solid State Reaction Method”.
It is used as a dopant because it is a good candidate to be a carbon source material for doping MgB2. The amount of C22H22O6
was varied between 0 and 9 wt % (0, 1.5, 3.0, 4.5, 6.0 and 9.0 wt%) of the total MgB2 bulks. Vertical levitation and lateral force
measurements were carried out with both Zero-field-cooled (ZFC) and Field-cooled (FC) regimes at temperatures of 25 and 30
K. It was found that the bis oxalate adding has a positive impact on the levitation and guidance properties of MgB2 bulk. Based
on observed values of levitation and guidance force, it can be concluded the 3 wt% C22H22O6 added sample is the best of the
studied samples. This results of this study are useful for the practical application in Magnetic Levitation Devices.
