Abstract

Hole-doped antiferromagnetic La₂CoO₄ has been known to possess intriguing electronic and magnetic phases due to the complex temperature and magnetic field dependent behavior of Co³⁺ ions. Here, we report on magnetic and dielectric observations in the half hole-doped La_1.5Sr_0.5CoO₄. A Griffiths-like phase has been observed in the high temperature region below T_G (∼244 K). At low temperature (∼55 K), a metamagnetic phase has been observed where antiferromagnetic correlations appear. On further cooling, a static weak antiferromagnetic ordering appears at ∼30 K, and a charge-spin glass state has been realized at ∼14 K.
