论文摘要
磁场上富勒烯c $ _ {60} $上的量子抗铁磁模型具有$ 4S $ $δS^z = 2 $的$ 4S $地面磁化不连续性，这是自旋量子数$ s $的函数，这些量子$ s $ $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $ s $。该分子可以看作是富勒烯c $ _ {20} $，插入式相互作用在足够强的情况下会产生不连续性。两种分子的抗铁磁ising极限起源于两个分子的不连续性。结果表明，空间对称性如何决定$ i_h $ fullerene分子的磁反应。
The quantum antiferromagnetic Heisenberg model on the fullerene C$_{60}$ in a magnetic field has $4s$ ground-state magnetization discontinuities with $ΔS^z=2$ as a function of the spin quantum number $s$ that disappear at the classical limit. The molecule can be seen as the fullerene C$_{20}$ with interpentagon interactions that generate the discontinuities when sufficiently strong. The discontinuities originate from the antiferromagnetic Ising limit for both molecules. The results show how spatial symmetry dictates the magnetic response of the $I_h$ fullerene molecules.
