Geometrically frustrated (GF) delafossite systems PdCrO2 and LiCrO2 have received some attention in recent years because of their interesting physical phenomena and also from the application point of view. Metallic PdCrO2 and insulating LiCrO2, consisting of layered triangular arrangement of Cr+3, exhibits antiferromagnetic nature with two dimensional (2D) frustration. Recent studies reveal the presence of the spin correlation in a wide temperature range well above magnetic ordering temperature TN. It is of interest to investigate whether the frustration can be released by the application of external pressure or magnetic field in metallic and insulating environment in this structure. We have carried out magnetization under external hydrostatic pressure (up to 10 kbar) and heat capacity under high magnetic field of 140 kOe on these systems. The result reveals robust nature of the frustrated antiferromagnetic system irrespective of whether compound is metallic or insulating. [ABSTRACT FROM AUTHOR] |
