| Popis: | We present magnetization and muon spin resonance ( μ SR ) data on the single layered manganite LaSrMnO4, nominally containing no holes. Magnetization data corroborate antiferromagnetic (AF) spin order but it also suggest additional static moments with a magnetic anisotropy parallel to the AF easy axis, at low temperatures. Our μ SR data confirm the existence of these statics moments and imply that they are in a metastable, frozen state. Upon heating, the metastability disappears and for the additional moments a very slow dynamic is detected. |
