我们发现CePtSi是一种新的重费米子和相干致密近藤晶格化合物,在70 mK以上没有磁性或超导转变。测量的磁贡献的电阻率,静态磁化率,和低温热容CePtSi的报告。这种化合物具有大的低温磁化率值(chi(2.4 K)= 24.9 × 10 - 3/ cm/sup 3/mol),并且具有重费米子化合物的特征,具有巨大的电子比热系数,伽马..约800 mJ/molX sup 2:.
We find that CePtSi is a new heavy-fermion and coherent dense Kondo-lattice compound with no magnetic or superconducting transition above 70 mK. Measurements of the magnetic contribution to the electrical resistivity, static magnetic susceptibility, and low-temperature heat capacity of CePtSi are reported. This compound has a large value of the low-temperature magnetic susceptibility (chi(2.4 K) = 24.9 x 10/sup -3/ cm/sup 3//mol) and, characteristic of heavy-fermion compounds, an enormous coefficient of the electronic specific heat, ..gamma..approx.800 mJ/molX sup 2: .
