Nearly free electrons in a 5d delafossite oxide metal

Understanding the role of electron correlations in strong spin-orbit transition-metal oxides is key to the realization of numerous exotic phases including spin-orbit–assisted Mott insulators, correlated topological solids, and prospective new high-temperat ...

Steep-slope Metal-Insulator-Transition VO2 Switches with Temperature-Stable High ION

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Michele Tamagnone, Wolfgang Amadeus Vitale, Antonio Paone

This work reports a detailed experimental investigation of the slope of the current switching between OFF and ON states exploiting the metal-insulator-transition in vanadium dioxide devices. The reported devices are CMOS compatible 2-terminal switches. We ...

Impact of the Normal Zone Propagations Velocity of High Temperature Superconducting Coated Conductors on Resistive Fault Current Limiters

Daniele Colangelo, Bertrand Dutoit

The engineering critical current (Ic) of the high temperature superconducting coated conductors (HTS-CCs), today available on the market, is not a uniform parameter and varies significantly along the length of the conductors. Moreover, commercial HTS-CCs h ...

Buffer influence on magnetic dead layer, critical current, and thermal stability in magnetic tunnel junctions with perpendicular magnetic anisotropy

Jean-Philippe Ansermet

We present a detailed study of Ta/Ru-based buffers and their influence on features crucial from the point of view of applications of Magnetic Tunnel Junctions (MTJs) such as critical switching current and thermal stability. We study buffer/FeCoB/MgO/Ta/Ru ...

Analysis of Internal-Tin Nb3Sn Conductors for ITER Central Solenoid

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov

Japan Atomic Energy Agency (JAEA) is procuring 100% of the ITER Central Solenoid (CS) conductors. The CS conductor is required to maintain the performance under 60000 pulsed electromagnetic cycles. JAEA tested two internal-tin Nb3Sn conductors for the CS a ...

Environmental stability of high-mobility indium-oxide based transparent electrodes

Christophe Ballif, Stefaan De Wolf, Monica Morales Masis, Ali Dabirian, Thanaporn Tohsophon

Large-scale deployment of a wide range of optoelectronic devices, including solar cells, critically depends on the long-term stability of their front electrodes. Here, we investigate the performance of Sn-doped In2O3 (ITO), H-doped In2O3 (IO:H), and Zn-dop ...

Critical Current Oscillations in the Intrinsic Hybrid Vortex State of SmFeAs(O,F)

Philip Johannes Walter Moll

In layered superconductors the order parameter may be modulated within the unit cell, leading to nontrivial modifications of the vortex core if the interlayer coherence length ξc(T) is comparable to the interlayer spacing. In the iron pnictide SmFeAs(O,F) ...

Determination of effective mechanical properties of a double-layer beam by means of a nano-electromechanical transducer

Tobias Kippenberg, Xiaoqing Zhou, Albert Schliesser

We investigate the mechanical properties of a doubly clamped, double-layer nanobeam embedded into an electromechanical system. The nanobeam consists of a highly pre-stressed silicon nitride and a superconducting niobium layer. By measuring the mechanical d ...

Progresses and challenges in the development of high-field solenoidal magnets based on RE123 coated conductors

Davide Uglietti

Recent progresses in the second generation REBa2Cu3O7-x (RE123) coated conductor (CC) have paved a way for the development of superconducting solenoids capable of generating fields well above 23.5 T, i.e. the limit of NbTi-Nb3Sn-based magnets. However, the ...

Quench studies of YBCO insulated and noninsulated pancake coils

Pierluigi Bruzzone, Rainer Wesche, Natalia Hanna Glowa

As a result of extremely high upper critical fields Bc2, high temperature superconductors (HTSs) have the potential to be used as high field insert coils in magnet systems where the background field is provided by low temperature superconductors (LTS). How ...
