论文摘要
我们使用模型的哈密顿量来研究锰矿中的关键现象。该哈密顿量包括远程应变相互作用，以及磁性参数和应变场之间的耦合。我们执行扰动重新归一化组（RG）分析，并计算静态临界指数，正确到单环水平。我们将RG结果与掺杂锰关键系统的许多实验进行了比较。我们的理论与关键指数的实验值非常吻合。
We use a model Hamiltonian to study critical phenomena in manganites. This Hamiltonian includes long-range strain interactions, and a coupling between the magnetic order parameter and the strain field. We perform a perturbative renormalization group (RG) analysis and calculate the static critical exponents, correct to the one-loop level. We compare our RG results with many experiments on doped manganite critical systems. Our theory is in excellent agreement with the experimental values for the critical exponents.
