Eu${}_{0.5}$Sr${}_{1.5}$MnO${}_4$: a three-dimensional XY spin glass

Abstract

The frequency, temperature, and dc-bias dependence of the ac-susceptibility of a high quality single crystal of the Eu${}_{0.5}$Sr${}_{1.5}$MnO${}_4$ layered manganite is investigated. Eu${}_{0.5}$Sr${}_{1.5}$MnO${}_4$ behaves like a XY spin glass with a strong basal anisotropy. Dynamical and static scalings reveal a three-dimensional phase transition near $T_g$ = 18 K, and yield critical exponent values between those of Heisenberg- and Ising-like systems, albeit slightly closer to the Ising case. Interestingly, as in the latter system, the here observed rejuvenation effects are rather weak. The origin and nature of the low temperature XY spin glass state is discussed.
