  Phase transitions of lanthanide monophosphides with NaCl-type structure at high pressures

  摘要：

  Lanthanide monophosphides LnP (Ln = La, Ce, Pr, Nd, Sm, Gd, To, Tm and Yb) with a NaCl-type structure have systematically been prepared at high temperatures. Using synchrotron radiation, X-ray diffractions of LnP have been studied up to 61 GPa at room temperature. The NaCl-CsCl transition for CeP is found at around 25 GPa. First-order phase transitions of LnP (Ln = La, Pr and Nd) with the crystallographic change occur at around 24, 26 and 30 GPa, respectively. The structure of the high pressure phases of these phosphides is a body center tetragonal structure (Ln: 0, 0, 0; P: 1/2, 1/2, 1/2; space group P4/mmm), which can be seen as the distorted CsCl-type structure. The Pr-P distance in the high pressure form of PrP is 2.789 Angstrom. This almost agrees with the sum of covalent radii of Pr and P The Pr-P bond has the covalent character at very high pressures. Similar results are also obtained for LaP and NdP. The pressure-induced phase transitions of SmP, GdP, TbP, TmP and YbP occur at around 35, 40, 38, 53 and 51 GPa, respectively. The structure of the high pressure phase is unknown. The phase transitions of LnP with many f-electrons are not due to the mechanism of the ordinary NaCl-CsCl transition. The transition pressures of LnP increase with decreasing the lattice constants in the NaCl-type structure, which decrease with increasing atomic number of the lanthanide atoms.

  The microscopic magnetic properties of the heavy-electron compound YbP have been investigated by 31 P NMR at temperatures from 0.38 to 600 K. The observations of both an abrupt decrease of 1/ T 1 at around 0.7 K and additional broadening of the spectrum below this temperature show that YbP orders magnetically at low temperatures. In the paramagnetic state, the Knight shift vs susceptibility plot exhibits

  Five new compounds were synthesized by heating mixtures of the elements at 600 - 1000 °C and investigated by powder and single crystal X-ray methods. EuMg₂P₂ (a = 4.280(1), c = 7.164(3) Å), EuMg₂As₂ (a = 4.393(1), c = 7.321(1) Å),EuMg₂Sb₂ (a = 4.695(1), c = 7.724(2) Å), YbMg₂Sb₂ (a = 4.650(1), c = 7.540(2) Å), and SrLiAlSb₂ (a = 4.584(3), c = 7.697(9) Å) crystallize with the CaAl₂Si₂ type structure (P3̄m1; Z = 1). The magnetic susceptibility of EuMg₂Sb₂ shows Curie-Weiss behavior with an experimental magnetic moment of 7.48(2) μ_B/Eu atom and a Weiss constant θ = 3.2(1) K. EuMg₂Sb₂ is ordered antiferromagnetically at 8.2(3) K. Magnetisation measurements at 4.5 K show a linear increase and a saturation for a magnetic moment of 5.9(1) μ_B/Eu at 5.5 T, indicating an almost parallel spin alignment with increasing field strength. 151Eu Mössbauer spectra at 78 K show an isomer shift of -11.69(5) mm/s, compatible with divalent europium. At 4.2 K we observe full hyperfine field splitting with 23 T. The ¹²¹Sb spectrum at 4.2 K shows a transferred hyperfine field of 8(2) T at an isomer shift of -7.9(3) mm/s. From the band structure of EuMg₂Sb₂ we draw the conclusion, that analogous compounds of trivalent rare-earth metals with CaAl₂Si₂ type structure should not exist due to electronic reasons.

  通过在 600 - 1000 °C 温度下加热这些元素的混合物，合成了五种新化合物，并通过粉末和单晶 X 射线方法对其进行了研究。EuMg2P2（a = 4.280(1)，c = 7.164(3)埃）、EuMg2As2（a = 4.393(1)，c = 7.321(1)埃）、EuMg2Sb2（a = 4.695(1)，c = 7.724(2)埃）、YbMg2Sb2（a = 4.650(1), c = 7.540(2) Å)和 SrLiAlSb2 (a = 4.584(3), c = 7.697(9) Å)以 CaAl2Si2 型结构 (P3̄m1; Z = 1) 结晶。EuMg2Sb2 的磁感应强度显示出居里-魏斯行为，实验磁矩为 7.48(2) μB/Eu 原子，魏斯常数 θ = 3.2(1) K。在 4.5 K 下的磁化测量显示出线性增长，在 5.5 T 时磁矩为 5.9(1) μB/Eu 时达到饱和，这表明随着磁场强度的增加，自旋排列几乎是平行的。在 78 K 时，151Eu 莫斯鲍尔光谱显示出-11.69(5) mm/s 的异构体位移，与二价铕相符。在 4.2 K 时，我们观察到 23 T 的全超频场分裂。121Sb 在 4.2 K 时的光谱显示出 8(2) T 的超频场转移，异构体位移为 -7.9(3) mm/s。根据 EuMg2Sb2 的能带结构，我们得出结论，由于电子学原因，不应该存在具有 CaAl2Si2 类型结构的三价稀土金属类似化合物。

  Low-temperature specific heat and its field-dependence up to 16T was measured in a stoichiometric single crystal of YbP. A sharp peak was observed at T-N = 0.53 K in zero magnetic field. Application of external field seems to induce a new magnetic phase above 11 T. The field dependence of the transition temperature in the high-field phase is different from that of the low field phase. The linear coefficient of the electronic specific heat is estimated as 120 mJ/mol.K-2 from low temperature specfic heat, suggesting heavy Fermion state in YbP.

  A large single crystal of stoichiometric YbP was grown by the mineralization method. We report the electrical resistivity, magnetoresistance, and Hall-effect measurements of this sample. These data are used to calculate the temperature dependences of the mobilities of electrons and holes as well as the carrier concentrations based on the simple two-band model. The results clearly indicate that transport properties in YbP are mainly determined by the conduction-band electrons, though an equal number of valence-band holes is present. The resistivity does not show the -lnT behavior characteristic of Kondo compounds. [S0163-1829(98)00819-4].
