    AnnotationWe present the experimental observation of the spin Seebeck effect in ε-Fe2-xAlxO3 (x=0 and 0.3) thin films with Pt detection layer. The films with 40–70 nm thicknesses were deposited by a spin-coating method on Y:ZrO2(100) substrates. The prepared films are highly oriented with the easy magnetic a-axis parallel to the film surface. The magnetic hysteresis loops measured for x=0 at room temperature with the magnetic field parallel to the surface exhibit coercive fields up to 11.6 kOe, which is so far the highest value of ε-Fe2O3 thin films. The spin Seebeck signal for x=0 increases proportionally to the film's thickness, which means that the critical thickness corresponding to the magnon propagation length is greater than 70 nm.
