摘要

在铁磁性伊辛和反铁磁性 XXZ 海森堡相互作用的情况下，研究了自旋-1/2 伊辛-海森堡畸变金刚石链在外加磁场存在下的基态，它表现出自旋的几何挫折。详细研究了量子波动、磁场和畸变对基态的影响。研究证实，零温磁化曲线可能在饱和磁化的零点和三分之一处出现中间高原。

Ground state of the spin-1/2 Ising–Heisenberg distorted diamond chain with ferromagnetic Ising and antiferromagnetic Heisenberg interactions

The ground state of the spin-1/2 Ising–Heisenberg distorted diamond chain in the presence of an external magnetic field is investigated in the case of the ferromagnetic Ising and antiferromagnetic XXZ Heisenberg interactions, that exhibits a geometric frustration of spins. The influence of the quantum fluctuations, the magnetic field, and the distortion on the ground state are studied in detail. It is established that the zero-temperature magnetization curve may show intermediate plateaus at zero and one-third of the saturation magnetization.

期刊介绍： Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies. Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
