(2014) 'Stripe disorder and dynamics in the hole-doped antiferromagnetic insulator La5/3Sr1/3CoO4.', Physical review B., 89 (2). 020405(R).
We investigate the magnetic ordering and dynamics of the stripe phase of La 5/3 Sr 1/3 CoO 4 , a material shown to have an hourglass magnetic excitation spectrum. A combination of muon-spin relaxation, nuclear magnetic resonance, and magnetic susceptibility measurements strongly suggest that the physics is determined by a partially disordered configuration of charge and spin stripes whose frustrated magnetic degrees of freedom are dynamic at high temperature and which undergo an ordering transition around 35 K with coexisting dynamics that freeze out in a glassy manner as the temperature is further reduced.
