Abstract

The resistive measurements were made to study the magnetic field-induced antiferromagnetic (AF) - weak ferromagnetic (WF) transition in La $_2$ CuO $_4$ single-crystal. The magnetic field (DC or pulsed) was applied normally to the CuO $_2$ 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 La $_2$ CuO $_4$ single-crystal in the parallel - to - CuO $_2$ layers direction. The results provide support for the 3-dimensional nature of the hopping conduction of this layered oxide.
