Resistive measurements were made to study the magnetic field-induced antiferromagnetic
(AF)—weak ferromagnetic (WF) transition in the La₂CuO₄ single crystal. The magnetic field (dc
or pulsed) was applied normally to the CuO₂ layers. The transition manifested itself in a drastic
decrease of the resistance in critical fields of 5–7 T. The study is the first to display the effect of
the AF–WF transition on the conductivity of the La₂CuO₄ single crystal in the direction parallel
to the CuO₂ layers. The results provide support for the three-dimensional nature of the hopping
conduction of this layered oxide.
