Here we present the extended experimental and theoretical study that explores various implications of the interaction between metallic and magnetic layers [2]. New experimental investigations include neutron scattering experiments, ac and dc magnetic susceptibility measurements, and electrical transport measurements in the wide temperature and pressure ranges, resulting in the new phase diagram for Co<sub>1/3</sub>NbS<sub>2</sub>. The theoretical work focuses on revealing the mechanisms of magnetic ordering and its suppression under pressure, starting from calculations of electronic structure and magnetic interactions. We conclude that magnetic couplings beyond nearest-neighbor in-plane interactions determine the nature of magnetic ordering. The suppression of ordering under pressure is ascribed to the shift in balance between super-exchange and RKKY magnetic couplings, leading to fully frustrated magnetic system.</span></p><p style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;" data-mce-style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 15px; text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;" data-mce-style="font-family: arial, helvetica, sans-serif;">[1] N.
