The effect of weak external magnetic fields on the conditions for implementing optical
bistability in the region of exciton absorption of layered semiconductors has been
theoretically investigated. By the example of the 2 H polytype of lead diiodide, it is shown
that, changing the strength of an external magnetic field, one can form conditions for
implementing bistability and effectively control the position and sizes of the hysteresis loop
of exciton absorption.
