The exchange coupling of magnetically ordered layers (MOLs) through a nonmagnetic metallic
 spacer was calculated. The induced magnetization in the spacer, taking into account the influence
 of an external magnetic field, was calculated, too. This calculation shows that the energy of coupling
 of the MOLs through the nonmagnetic metallic spacer is a long-periodic function of the
 spacer’s thickness and magnetic field, i.e., the exchange coupling between the layers varies from
 ferromagnetic to antiferromagnetic and vice versa depending on the spacer’s thickness and magnetic
 field. Also this calculation shows that in nonferromagnetic spacer the induced magnetization
 can undergo many complete rotations depending on distance to the boundaries with the MOLs.
 Moreover, absolute value of induced magnetization nonmonotonously decays with distance from
 the interfaces inside the spacer. It is shown that the character of the decay of absolute value magnetization
 from the interfaces into the interior of the spacer is influenced by magnetic field.
