We present the observation oftransverse thermopower, orplanar Nernst Effect(PNE), andplanarHall Effect(PHE) in patterned ultrathin film (∼8 nm) of La0.7Sr0.3MnO3(LSMO). For PNE, a heat current was applied in-plane of the film (by creating a temperature gradient ∇T) whereas an in-plane current of 100 μA was applied for measuring PHE. Even for a temperature difference of ΔT = 5 K the planar Nernst effect in LCMO ultrathin film (∼8 nm) shows a coercivity of ∼3 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.
