Abstract

We propose a simple method to create a local magnetic field minima for the magnetic trapping and confining of excitons. We observe an enhanced spatially resolved photoluminescence of the optically active heavy-hole excitons concentrated at the confining region in a multiple quantum wells system. We draw the attention to consider the proposed trapping mechanism as an approach to reach the Bose-Einstein condensate limit of excitons.
