Abstract
We present the observation of transverse thermopower, or planar Nernst Effect (PNE), and planar Hall Effect (PHE) in patterned ultrathin film (â¼8 nm) of La0.7Sr0.3MnO3 (LSMO). For PNE, a heat current was applied in-plane of the film (by creating a temperature gradient âT) whereas an in-plane current of 100 μA was applied for measuring PHE. Even for a temperature difference of ÎT = 5 K the planar Nernst effect in LCMO ultrathin film (â¼8 nm) shows a coercivity of â¼3 Oe and confirms the ferromagnetic nature of the thin film. The angular dependence of transverse voltage in PNE shows a four-fold sinθ cosθ dependence symmetry at 250 K, which is consistent with the planar Hall effect measurement.
