DC magnetization measurements were performed on the mercuD-based superconductor HgBa2Ca3Cu4Oto+a . The analysis of the magnetic hysteretic behavior of the sample either with temperature or with field, allowed the determination of the irreversibility line of this compound, as well as temperature and
Samples of HgBa2Ca2Cu3Os.6 were successfully prepared and investigated. By examining the X-ray diffraction, mission electron microscopy, magnetization and resistivity, we found that HgBa2CaaCusOs+8 possesses an orthorhombic structure with lattice parameters o--5.451(2) A, b=5.432(2) ,~ and c= 15.826
Well developed single crystals of the mercury compound HgBa2Ca2Cu3OS+d have been obtained in single step synthesis under normal pressure conditions. Samples in the submillimeter range give a sizeable diamagnetic signal which allowed a systematic study of the magnetization anisotropy both before and
