摘要: 本文利用一种新的自旋玻璃模型-无规格点模型,对掺杂度为0.5%的自旋玻璃CuMn进行了MC模拟计算**。发现低场磁化率存在明显的尖峰,磁比热cm仅有宽广峰。

Abstract: Using a new spin glass model-random Lattice model, MC Simulation has been calculated for spin glass system Cu0.995Mn0.00 5, It is found that there exists a sharp cusplike peak in the low-field susceptibility and a broad round peak in the magnetic specific heats.
