$5d$ iridium oxides are of huge interest due to the potential for new quantum states driven by strong spin-orbit coupling. The strontium iridate Sr$_2$IrO$_4$ is particularly in the spotlight because of the so-called $j_\text{eff}=1/2$ state consisti

Performances of Neutron Scattering Spectrometers on a Compact Neutron Source

Autor: Fabrèges, Xavier, Menelle, Alain, Ott, Frédéric, Chauvin, Nicolas, Schwindling, Jérôme, Letourneau, Alain, Marchix, Anthony, Alba-Simionesco, Christiane

There is currently a big effort put into the operation and construction of world class neutron scattering facilities (SNS and SNS-TS2 in the US, J-PARC in Japan, ESS in Europe, CSS in China, PIK in Russia). On the other hand, there exists a network o

Tunnel diode oscillator measurements of the upper critical magnetic field of FeTe0:5Se0:5

Autor: Audouard, Alain, Drigo, Loïc, Duc, Fabienne, Fabrèges, Xavier, Bosseaux, Ludovic, Toulemonde, Pierre

Temperature dependence of the upper critical magnetic field (Hc2) of single crystalline FeTe0.5Se0.5 (Tc = 14.5 K) have been determined by tunnel diode oscillator-based measurements in magnetic fields of up to 55 T and temperatures down to 1.6 K. The
