TL;DR
This study investigates how the freezing of antiferromagnetic domain boundary motion in lightly doped La_{2-x}Sr_{x}CuO_{4} leads to spin-glass behavior, using resistivity and magnetization measurements.
Contribution
It reveals that the freezing of transverse AF domain boundary motion causes spin-glass features in lightly doped La_{2-x}Sr_{x}CuO_{4}.
Findings
Freezing of AF domain boundary motion observed.
Spin-glass features linked to boundary freezing.
Transport and magnetic properties show domain boundary dynamics.
Abstract
Resistivity and magnetization measurements are used for studying the transverse sliding of AF domain boundaries in lightly doped La_{2-x}Sr_{x}CuO_{4}. We discuss that it is the freezing of the transverse boundary motion that is responsible for the appearance of ``spin-glass'' features at low temperatures.
