Presence of parimagnetism in HoCo2 under hydrostatic pressure

Original language description

This paper deals with a pressure evolution of newly observed phenomenon parimagnetism in HoCo2. HoCo2 containing localized Ho magnetic moments and itinerant Co magnetic moments order ferrimagnetically below T-C = 79.5 K at ambient pressure. The corresponding Ho and Co magnetic sublattices are ferromagnetic and coupled mutually antiparallel. In paramagnetic range, the Co moments form ferromagnetic clusters which hold short range antiparallel configuration with the nearest Ho moments at temperatures up tothe flipping temperature T-f = 125 K. The decay of Co clusters was observed by muon spin relaxation spectroscopy (mu SR) at T* similar to 170 K. Our results of AC-magnetic susceptibility and zero-field mu SR measurements of HoCo2 at ambient and hydrostatic pressures presented in this paper reveal strong pressure dependence of the characteristic temperatures which is closely related to the itinerant character of Co magnetism and variations of exchange interactions.
