Temperature dependence of AC susceptibility using a general magnetization model

The influence of KClO 3 addition on the magnetic properties and microstructural parameters (grain size, grain boundaries) of high-temperature superconductors (HTSC) with nominal composition Y (1−0.2x) Ba (2−0.2x) K x Cu 3 O y (x = 0-0.40) were investigated. The ac complex susceptibility χ ac = χ − iχ was recorded as a function of temperature and concentration of KClO 3 at various ac magnetic fields up to 2 mT. The data were analysed using the relation h = a(1 − T m /T c ) n , where T m represents the intergranular peak temperature of the imaginary component χ . The value of a is found to increase for doped samples, which suggests enhanced flux pinning due to the KClO 3 addition. The dc susceptibility as a function of temperature was measured by means of a SQUID magnetometer in field-cooled cooling (FCC) and field-cooled warming (FCW) modes in magnetic fields in the range 10 mT µ 0 H a 7 T on KClO 3 -doped and pure YBCO samples. The Meissner curves reveal that the samples are single phase in all applied fields, but the low-temperature behaviour of the samples with KClO 3 additions is different from that of pure YBCO.
