Electron spin interactions and Meissner effect

In the framework of spin interactions, we study a two-dimensional system of electrons with antiferromagnetic arrangement of spins considering the elec tron a charged quantized vortex-type object. In the presence of a magnetic held the system starts to move due to corroborated action of the vortex pop ulation. The developed currents calculated in a hydrodynamic approach creat e a magnetic field opposed to the applied magnetic field, leading to the ap pearance of Meissner effect.
