Abstract

In Pr_0.7Ca_0.15Ba_0.15MnO₃ manganite, the spin dynamics is studied by the method of electron paramagnetic resonance (EPR). The analysis showed that at the temperature Т_L ≈T_min, which corresponds to the minimal width of the EPR line, the shape of lines of absorption spectra is perfectly described by a single Lorentzian. At other temperatures (not Т_L), the absorption lines of the EPR spectra are asymmetric, which is caused by their exchange broadening at Т < Т_L or hopping conductivity at T > Т_L.

Pr0.7Ca0.15Ba0.15MnO3锰酸盐的电子顺磁共振谱线形状

摘要

在Pr _0.7 Ca _0.15 Ba _0.15 MnO ₃锰酸盐中，采用电子顺磁共振(EPR)的方法研究了自旋动力学。分析表明，在对应于 EPR 线的最小宽度的温度Т _L ≈ T _min下，吸收光谱线的形状可以由单个洛伦兹完美地描述。在其他温度下（不是Т _L），EPR 光谱的吸收线是不对称的，这是由于它们在Т < Т _L处的交换展宽或在T > Т _L处的跳跃电导率引起的。
