Static and dynamic magnetic properties of K3CrO4

•The magnetic properties of K3CrO4 are reported for the first time.•The structure, static and dynamic magnetic properties are investigated.•A paramagnetic-glassy canted antiferromagnetic transition occurs below 36 K.•The onset of cluster glass behavior below 20 K is analyzed by dynamic scaling laws.•Field-induced temperature-dependent transitions of unknown nature are detected at 3–10 K. We report on the magnetic properties of geometrically frustrated K3CrO4, in which Cr5+ cations are arranged on a distorted pyrochlore lattice. The crystal structure, static and dynamic magnetic properties of the compound are investigated in detail. A combination of DC and AC magnetic susceptibility measurements together with thermoremanent magnetization decay measurements reveal several magnetic transitions: the onset of glassy canted antiferromagnetic order occurs at 36 K, followed by the appearance of ferromagnetic/ferrimagnetic cluster glass behavior below the freezing temperature of 20 K. Further field-induced, temperature-dependent transitions are observed in the range 3–10 K. The frequency dependence of the freezing temperature for the cluster glass state is analyzed on the basis of dynamic scaling laws including the critical slowing down formula and the Vogel-Fulcher law.
