“…The AFM transition, however, can not be resolved within the resolution of our experiment. This stands in sharp contrast to other reports where the entrance in the AFM state manifests by a distinct peak at T N for all current directions before ρ steadily decreases upon further lowering temperature [9,11]. At T 1 the resistivity drops significantly as can be inferred from Fig.…”

“…In this report we present first results on our Ce 3 Al 11 single crystals. A distinct difference with published work [9][10][11][12] is found. A small single crystal of size 38×133×153 µm 3 was studied by XRD (see for details Tab.…”

“…We speculate that in Ce 3 Al 11 with larger unit-cell volume, T N and T 1 are merged. This could explain the sharp and slight deviant second-order behavior of the AFM transition in C/T measured by Garde et al [11]. Hence with increasing pressure, i. e. , reducing the unit-cell volume, T N and T 1 would split.…”

“…Afterwards the ampule was cooled down at a Low temperature dependence of the (a) electronic specific heat and (b) resistivity with current j applied parallel[100]. C e /T has been obtained by subtracting La 3 Al 11 from Ref [11]…”

We report a study on a single crystal of the ordered heavy fermion compound Ce 3 Al 11 grown by Al-flux. Three transitions are observed. A ferromagnetic one at T C = 6.2 K which is followed by an antiferromagnetic one at T N = 3.4 K and a third one at T 1 = 2.7 K. This lower one has not been reported before. It's origin is unknown, and unlike the other two the transition is of first order type. We infer the appearance of the T 1 transition to a smaller unit-cell volume of our samples which acts like hydrostatic pressure.

“…The electrical resistivity [7] and magnetic effects [8] of Ce3Al11 were also studied under pressure. Besides the cerium compound, the physical properties of the series of RE3Al11 with RE = La-Nd and Sm have been studied [9,10]. During attempts to synthesize CeNiGa2 from Al-flux reactions, single crystals of the title compound were obtained.…”

Structure and Magnetic Properties of Ce3(Ni/Al/Ga)11—A New Phase with the La3Al11 Structure Type

et al. 2014

Single crystals of Ce3(Ni/Al/Ga)11 were obtained from an Al flux reaction. Single crystals of the title compound crystallizing in the orthorhombic space group Immm (No. 71, Z = 2) with a = 436.38(14), b = 1004.5(3) and c = 1293.4(4) pm. This is a standardized unit cell of the previously published La3Al11 structure type. Wavelength dispersive microprobe provides the composition of Ce3.11(1)Ni0.03(1)Al8.95(1)Ga1.90(1). Single crystal refinement provides the composition Ce3Ni0.08Al9.13Ga1.78 with substitution of the Ni and Ga on the Al1 and Al4 sites with the Al2 and Al3 solely occupied by Al. Magnetic susceptibility measurements reveal antiferromagnetic ordering with TN = 4.8 K and there is no evidence for a ferromagnetic ordering that has been reported for Ce3Al11. The effective magnetic moment was found to be μeff = 1.9μB/Ce, which is lower than the expected value for trivalent Ce (2.54μB/Ce). OPEN ACCESSCrystals 2015, 5 2
