Evolution of magnetism in single-crystalCa2Ru1−xIrx

Abstract

We report structural, magnetic, transport and thermal properties of single-crystal

Suppressed antiferromagnetic ordering and enhanced electrical conduction in doped iridate Sr2−xPrxIrO4

“…where k B is Boltzmann constant, l denotes the localization length, and N(E F ) represents the density of states at the Fermi level. Based on previously estimated value of N(E F ) at 10 28 [13], confirming the validity of the VRH mechanism. We find that T 0 decreases with increasing the Pr concentration.…”

“…In order to investigate more physical properties of the samples, we measured the low-temperature specific heat. From previous reports, we have known that the heat capacity of Sr 2 IrO 4 shows no corresponding anomaly at the magnetic ordering temperature 240 K, which is one of the characters of the J eff =1/2 insulator [27,28]. Thus we only measured the heat capacity of a selective sample, i.e., x=0.1 sample in the range of 2-20 K, which is shown in figure 7(a).…”

“…4). This behavior is absent in Rh doped Sr 2 IrO 4 but is observed in Ca 2 Ru 1-x Ir x O 4 due to the strong interaction between Ru 4d-and Ir 5d-electrons [29]. For x=0, M a is larger than M c because the magnetic moment lies within the basal plane [7].…”

Catalyst-assisted probabilistic coherence distillation for mixed states

“…Thus, a central problem in the resource theory of coherence is the coherence distillation, i.e., the process that extracts target pure coherent states from initial mixed states via incoherent operations. Recently, this problem has generated a great deal of interest [16,[18][19][20][21][22][23][24][25][26][27][28]. The coherence distillation of mixed states via various incoherent operations was studied in the asymptotic limit in Refs.…”
