his paper presents the results of a high pressure study on the ferrimagnetic compound ErCo2,which exhibits at ambient pressure magnetic ordering below TC=33 K, where the localized Er magnetic moments order ferromagnetically, and the itinerant moments in the Co sublattice, align antiparallel to the Er moments. In the paramagnetic range, clustering of the Co moments is observed below Tf~100 K for which the term "parimagnetism" has been proposed. In contrast to the pronounced peak in the AC susceptibility data at TC only a tiny "bump" shows up at Tf. The decrease of both TC and Tf with applied hydrostatic pressure has been observed, the first one being in agreement with previously published data.
