Properties of inductance and magnetic penetration depth in (103)-orientedYBa2Cu3O7−δthin films

YBa 2 Cu 3 O 7−δ nanorings to probe fluxoid quantization in High Critical Temperature Superconductors

“…Moreover, it represents a clear evidence of a uniform vorticity of the order parameter inside the rings, which is a consequence of the high degree of homogeneity of these nanostructures. These results represent solid grounds for future experiments on underdoped YBCO nanorings and on nanorings with various YBCO orientations [27], where different values of the fluxon might be detected.…”

Resistive state triggered by vortex entry in YBa 2 Cu 3 O 7−δ nanostructures

“…3(c)). The parameter b L ðTÞ, defined as I max C ðTÞL loop ðTÞ=U 0 , with L loop total inductance of the SQUID loop and U 0 flux quantum, can be numerically calculated by solving the Maxwell and London equations describing the Meissner state on our SQUID geometry [31]. For the temperature dependence of the loop inductance we have again used the two fluid model for the London penetration depth, on which the kinetic inductance of the wires (which gives the main contribution to L loop ) is strongly dependent.…”

Low capacitance HTS junctions for single electron transistors

“…The current sent through the injection lines acts on the Josephson current in the same way as an external magnetic field [5]. The injection current needed to get one period of the SQUID modulation can be related to L by DI ¼ / 0 =L [5]. All electrical measurements were done at 280 mK using an Oxford Instruments Heliox VL 3 He system.…”

“…The seedlayer is patterned using a technique based on an amorphous carbon mask, Ar ion milling and e-beam lithography. More details are available in [5]. A YBCO film is deposited using PLD.…”
