“…Analogous compounds were observed also within the EreCueAl systems [10]. A similar impurity phase was observed also in previously studied compounds but no observable influence on the magnetic properties of studied samples was detected by the neutron diffraction and the bulk property measurements, respectively [2,7].…”

“…The temperature independent term c 0 was found to be of the order of 10 À9 m 3 /mol in all cases, comparable to the values of the temperature independent susceptibility of YCuAl and LuCuAl [7].…”

“…The magnetic structure of the DyNi 0.7 Cu 0.3 Al compound was not determined due to low-quality diffraction patterns for this compound. The parameters obtained from the bulk data of DyCuAl were taken from [7], whereas the parameters of the magnetic structure were obtained from our results of the powder neutron diffraction experiment at 1.8 K. Signs of short-range order could be visible on samples with 0.6 x 0.9. Table 2 are enhanced due to low intensities of the AF reflections at 1.6 K (see Fig.…”

“…At temperatures below T 1 ¼ 15 K an antiferromagnetic component of the Dy moment perpendicular to c appears [4e6]. The magnetism in DyCuAl seems to be analogous; the only difference is observed in the temperatures of the magnetic phase transitions: T C ¼ 28 K and T 1 ¼ 12 K. The bulk magnetization data fit well with this scenario [7]. The aim of the present study is to follow the evolution of magnetism within the Dy(Ni,Cu)Al series with respect to the Cu for Ni substitution within the transition-metal sublattice with special emphasis on the possible loss of the long-range magnetic order by studying bulk material properties (magnetization, AC magnetic susceptibility, heat capacity) and also microscopic aspects of magnetism by neutron diffraction.…”

was the first to examine the phase relations in the Al-rich corner employing X-ray, metallographic and chemical analysis and micro-hardness measurements on a total of 130 alloys. Ce-rich specimens were prepared from 99.9 mass% pure Al, 98.6% pure Ce and 99.89% pure Cu by melting the constituents; Ce-poor specimens were prepared from a "hardener" alloy in Al 2 O 3 -crucibles under carnallite. All the alloys were annealed in vacuum at 500 and 400 2°C for 120 or 240 h, respectively and were finally quenched in toluene. Lattice parameters were measured with a claimed precision of 0.01 pm on polished sample surfaces in a back-reflection camera at 400 and 500°C for three series of alloys with constant amounts of 1 mass% Ce, 5 mass% Ce and 5 mass% Cu, respectively. The plots of the unit cell dimensions versus concentration were used to establish the extension limits and vertices of the two-and three-phase equilibria of the (Al) solid solution. A series of successive crystallographic investigations [
