A new configuration of cobalt magnetic moments with respect to rare-earth ones on local level, named as parimagmetism, surviving above the Curie temperature was determined few years ago for ErCo2. Occurrence of parimagnetism has recently been confirmed also for HoCo2.
In this paper we present results manifesting considerable composition and hydrostatic-pressure influence on characteristic temperatures of magnetism in Ho(Co1-xSix)(2) compounds and draw a preliminary scenario analyzing the exchange interactions involved.
