【 摘 要 】
Microwave absorption studies have been carried out on MgB2 superconductor using a standard X-band EPR spectrometer. The modulated low-ï¬eld microwave absorption signals recorded for polycrystalline (grain size ∼ 10ðœ‡m) samples suggested the absence of weak-link character. The ï¬eld dependent direct microwave absorption has been found to obey a $sqrt{H}$ dependence with two different slopes, which indicated a transition from strongly pinned lattice to flux flow regime.
