Abstract

We develop a spin wave theory for the canting antisymmetrism bj using Holstein-Primakoff transformation, and study the field-induced transition in La₂Cu0₄ when the magnetic field is applied perpendicular to the CuO₂ plane. The temperature dependence of the critical magnetic field predicted by our theory agrees fairly well with the experiment at low temperature.
