“…Such a result is consistent with the experimental result that the magnetic transition is accompanying with a structural transition as reported by Kanaya et al [17,18]. The lattice parameter b increases abruptly by 4%, while the a and c decrease by less than 1 % below 270 K. Our result is different from the pervious work where the resistivity of CrAs increases with decreasing temperature below 270 K [16]. The behavior that the magnetic transition occurs concomitantly with a structural distortion is similar to that of 122 systems of iron-pnictides.…”

High quality single crystal CrAs was grown by Sn flux method. The results of magnetic susceptibility and electrical resistivity are reported in a temperature range of 2 to 800 K. At low temperatures, a T 2 dependence of resistivity is observed showing a Fermi-liquid behavior. The Kadowaki-Woods ratio is found to be 1×10 −5 μΩ cm mol 2 K 2 mJ −2 , which fits well to the universal value for many correlated electron systems. At about 270 K, a clear magnetic transition is observed with sharp changes of resistivity and susceptibility. Above 270 K, a linear-temperature dependence of the magnetic susceptibility is observed up to 700 K, which resembles the T-dependent magnetic susceptibility of parents of iron-pnictides superconductors.CrAs, Kadowaki-Woods ratio, magnetic phase transition, linear T-dependent magnetic susceptibility PACS: 74.62.Bf, 74.25.Gz

“…The lattice parameters are a=5.649 Å, b=3.463 Å, and c = 6.2084 Å [16]. The structural, magnetic, specific heat, transport, and neutron scattering measurements have been reported for polycrystal materials [16][17][18][19]. The compound has a phase transition at 800 K from the hexagonal NiAstype to the orthorhombic MnP-type.…”

“…This indicates our sample should have larger change on cell volume. In CrAs 1 x P x [11], it was found that the T N is related to the b-axis lattice parameters. The different single crystal growth condition, growth temperature and cooling procedure, may lead to different stress in as-grown crystal.…”

“…The transition is first order, showing a hysteresis between 260-270K [8]. Below the transition, the b-axis lattice parameter b increases by about 4%, while the a-axis lattice parameter (a) and c-axis lattice parameter (c) decreases by about 0.3% and 0.5%, respectively [11]. Just recently, superconductivity was observed in CrAs under pressure (P ) when its helical AFM transition was suppressed, by two different groups Wei Wu et al [12] and Hisashi Kotegawa et al [13].…”

Mono-arsenide CrAs, endures a helical anti-ferromagnetic order transition at ~ 265 K under ambient pressure. Recently, pressure-induced-superconductivity was discovered vicinity to the helical anti-ferromagnetic order in CrAs [Wei Wu et al., Nature Communications 5, 5508 (2014).]. However, the size of crystal grown via tin flux method is as small as 1 mm in longest dimension. In this work, we report the single crystal growth of CrAs with size of 1 × 5 × 1 mm 3 via chemical vapor transport method and its physical properties.

“…This antiferromagnetic state can be completely suppressed by applying 7 kbar [12,13], or by substituting 5% of phosphorous for arsenic, i.e. CrAs 0.95 P 0.05 [14].The magnetic behaviour of phosphorous substituted samples is similar to that of CrAs under high pressure, and hence phosphorous acts as the chemical pressure analogous to other systems such as BaFe 2 (As 1−x P x ) 2 [15]. Concomitant with the suppression of the helimagnetic state, superconductivity can be induced in CrAs by pressure.…”

Quasilinear quantum magnetoresistance in pressure-induced nonsymmorphic superconductor chromium arsenide

In conventional metals, modification of electron trajectories under magnetic field gives rise to a magnetoresistance that varies quadratically at low field, followed by a saturation at high field for closed orbits on the Fermi surface. Deviations from the conventional behaviour, for example, the observation of a linear magnetoresistance, or a non-saturating magnetoresistance, have been attributed to exotic electron scattering mechanisms. Recently, linear magnetoresistance has been observed in many Dirac materials, in which the electron–electron correlation is relatively weak. The strongly correlated helimagnet CrAs undergoes a quantum phase transition to a nonmagnetic superconductor under pressure. Here we observe, near the magnetic instability, a large and non-saturating quasilinear magnetoresistance from the upper critical field to 14 T at low temperatures. We show that the quasilinear magnetoresistance may arise from an intricate interplay between a nontrivial band crossing protected by nonsymmorphic crystal symmetry and strong magnetic fluctuations.
