  Magnetic and Mössbauer-effect studies ofU6Fe hydride

  摘要：

  The dc magnetization, ac susceptibility, heat capacity, and Mossbauer effect for U6FeH17 and beta-UH3 have been examined as a function of temperature (4.2-300 K) and magnetic field up to 140 kOe. The U6FeH17 crystallizes in the Pm3n space group where the metal arrangement is like that of beta-W. The compound turned out to be a ferromagnet with a transition temperature of 173 K differing only slightly from that of beta-UH3. The saturation magnetization of U6FeH17 at 140 kOe and at 4.2 K is smaller than that for beta-UH3. The temperature dependence of the ac susceptibility showed a sharp maximum of the chi' and chi'' at the para-ferromagnetic transition temperature for both investigated hydrides. In the U6FeH17 hydride another steplike anomaly at about 140 K has been observed. This anomaly has been confirmed by heat capacity measurements. No such anomaly in beta-UH3 hydride has been reported for both mentioned above types of experiment. The valence-charge-density distribution and the main components of the electric field gradient tenser were calculated using the modified Thomas-Fermi approach. Mossbauer spectra analysis has shown that the iron atoms preferably occupy (6c) sites in the U6FeH17 lattice. It has been concluded that the [110] axis could be an easy magnetization direction in U6FeH17 hydride.

  Abstract The heat capacity C p ( T ) of U 6 FeH 15 hydride was meausured in the temperature range 4.5–255 K. The complex anomaly with two critical temperatuers was observed, which arises from the magnetic phase transitions. The low-temperature maximum reveals thermal hysteresis. The higher temperature anomaly is close to the T c observed for β-UH 3 . The change in entropy of the transitions was estimated

  Abstract The penetration depths, λ(T), of the heavy-fermion uranium-based superconductors U6X (X = Fe, Co, Mn) have been measured as a function of temperature at ∼ 35 MHz. It was found that the temperature dependence of λ(T) for these compounds agrees well with the BCS theory. However, the values of λ(0) are large. By comparing the Slater-Pauling curve of the X elements with λ(0)-1 for the U6X superconductors

  摘要 重费米子铀基超导体 U6X（X = Fe、Co、Mn）的穿透深度 λ(T) 作为温度的函数在 ~ 35 MHz 下进行了测量。发现这些化合物的 λ(T) 的温度依赖性与 BCS 理论非常吻合。然而，λ(0) 的值很大。通过将 X 元素的 Slater-Pauling 曲线与 U6X 超导体的 λ(0)-1 进行比较，我们发现 λ(0)-1 与元素 X 的饱和自旋矩成正比，表明存在相关性这些 U6X 超导体的超导性与 X 元素的磁性之间。
