| Abstract: | The anisotropy of magnetic critical current density in HgBa2CuO40 has been investigated. HgBa2CuO40 was synthesized from the mixed powders of HgO, BaO and CuO in evacuated quartz tube at 750 C for lh. As-prepared HgBa2CuO4 was annealed in flowing argon at 300!C for 6h. Pulverized sample was aligned by a magnetic field of 8T in resin. The U- loop measurements of magnetically aligned crystalline HgBa2CuO4d were performed at 4.2K. The width of hysteresis loop, M b in the a-b plane and Ac along the c-axis, were calculated. The anisotropy of the width of hysteresis loop was observed, 1 .6SIUcor b/Mcorcs3. 1 in magnetic field up to 9T. The critical current densities, Jcb in the a-b plane and Jcc along the c-axis, were determined. The Jcb at 4.2K in lT was found to be equal to 1 .6x106A/cm2. |
