Magnetic properties of Pr1-xSr1+xMnO4 (0.3 <= x <= 0.8) single crystals

Abstract

We report the magnetic properties of Pr1-xSr1+xMnO4 single crystals in the composition range 0.3 less than or equal to x less than or equal to 0.8. All the compositions studied show highly anisotropic spin-glass type magnetic ordering at low temperatures. Some of the compositions (x > 0.6) exhibit a broad maximum in the magnetic susceptibility above 100 K, highlighting the 2D magnetic interactions in these compounds. A possible charge ordering transition is observed around 265 K for the x = 0.8 compound.
