摘要翻译:
在精确装饰-迭代映射变换的框架内,研究了自旋1/2和自旋1的混合Ising-Heisenberg铁磁体在由相互连接的金刚石组成的装饰三角晶格上的性质。结果表明,两个海森堡自旋的类金刚石装饰引起了不同的临界行为,包括具有两个连续临界点的重入相变。

英文摘要:
The mixed spin-1/2 and spin-1 Ising-Heisenberg ferromagnet on the decorated triangular lattice consisting of inter-connected diamonds is investigated within the framework of an exact decoration-iteration mapping transformation. It is shown that the diamond-like decoration by a couple of the Heisenberg spins gives rise to a diverse critical behaviour including reentrant phase transitions with two consecutive critical points.
