Back Cover: Possible existence of field‐induced Josephson junctions (Phys. Status Solidi B 9/2012)

Abstract

The existence of field‐induced junctions opens up possibilities for very easy manufacture of electronic devices that show no dissipation and have very simple architecture. They can be created by putting ferromagnetic or ferroelectric material on top of a superconductor. Their properties can be tuned in a continuous manner. The transition from the weak‐link regime to the tunneling regime is demonstrated by Pomorski and Prokopow (pp. ). This permits building tunable single Josephson junctions, arrays and matrices of Josephson junctions, SQUIDs, current limiters, qubits and a broad range of logical gates. Apart from the applications the new family of Josephson junctions also provides opportunities for studying the fundamental physics of magnetism and vortices.

“…Experimental [11,22] contribute to electron pairing. [23,24] Thus, the superconducting and magnetic behavior of the phase diagram is important when investigating the correlation between magnetism and superconductivity [25] typically in LCCO system. To realize this, we have obtained the expression for T c and T N as a function of doping such as magnetic fields and charge carriers.…”
