Internally assembled ring-bundle-barrier Bi-2223 tapes with a Rutherford type stranded structure were optimised with respect to low coupling losses. They had resistive barriers of a mixture of SrCO 3 and SrZrO 3 around the strands and around the cent

Ac-loss and coupling current time constant measurements were performed with a large variety of Bi-2223 tape conductors at 4.2 and at 77 K. Single tapes in a perpendicular field as well as stacks of tapes in perpendicular and parallel fields were inve

The AC losses in multifilamentary Bi(2223) tapes in external magnetic fields are dominated by the hysteresis losses in the superconducting filaments and by coupling current losses in the normal conducting matrix. In the last years great effort has be

We report thermal-expansion and specific-heat data of the series La 1 - x Ca x CoO 3 for 0 ⩽ x ⩽ 0.3 . For x = 0 the thermal-expansion coefficient α ( T ) features a pronounced maximum around T = 50 K caused by a temperature-dependent spin-state

The exact role of catalysts, such as titanium, scandium, or cerium, in improving the hydrogen kinetics in NaAlH4 is not completely understood. Here, we studied the local structure of scandium and the formation of different species in ScCl3-doped NaAl
