论文摘要
对tc = 0.32 k的重费超导体CE3PTIN11进行了核四极共振（NQR）测量。两种磁性磁力转移tn1 = 2.2 k and Tn2 = 2.0 = 2.0 = 0 k.中，自旋 - 静态放松率1/T1和NQR光谱的温度依赖性在CE（2）站点起着主要作用，CE（1）位点的磁矩也在一定程度上做出了贡献。虽然对于TN2 <t <tn1而出现了相称的抗铁磁有序状态，但建议对T <tn2进行部分不均一的抗磁磁有序状态。
Nuclear quadrupole resonance (NQR) measurements were performed on the heavy fermion superconductor Ce3PtIn11 with Tc = 0.32 K. The temperature dependence of both spin-lattice relaxation rate 1/T1 and NQR spectra evidences the occurrence of two successive magnetic transitions with TN1 = 2.2 K and TN2 = 2.0 K. In successive magnetic transitions, even though the magnetic moment at the Ce(2) site plays a major role, the magnetic moment at the Ce(1) site also contributes to some extent. While a commensurate antiferromagnetic ordered state appears for TN2 < T < TN1, a partially incommensurate antiferromagnetic ordered state is suggested for T < TN2.
