Short-range magnetic ordering in URh0.7Ru0.3Ge
The magnetic properties of URh0.7Ru0.3Ge were investigated by means of ac susceptibility, dc magnetization, specific heat and electrical resistivity measurements. We observed a maximum of the ac susceptibility at Tmax = 2.9 K and its frequency dependence, but no spontaneous magnetization at 2 K. An...

Summary: | The magnetic properties of URh0.7Ru0.3Ge were investigated by means of ac susceptibility, dc magnetization, specific heat and electrical resistivity measurements. We observed a maximum of the ac susceptibility at Tmax = 2.9 K and its frequency dependence, but no spontaneous magnetization at 2 K. An alternative scenario for the observed feature, for example, spin-glass freezing, is not confirmed by dc field dependences of the ac susceptibility and dc magnetization. The data from specific heat and electrical resistivity studies down to 2 K do not suggest long-range magnetic ordering, and point to spin-fluctuation behaviour of the alloy. We have estimated a spin-fluctuation temperature of ~27 K and Stoner enhancement factor of ~490. The experimental data are discussed in the framework of spin-fluctuation theories. |
