We demonstrate the effect of substrates on the temperature change induced by the anomalous Ettingshausen effect in ferromagnetic thin films. The experimental results show that, in comparison with conventional experiments using bulk substrates, the temperature modulation due to the anomalous Ettingshausen effect in Ni films can be enhanced by more than an order of magnitude using suspended membrane substrates, which reduce thermal dissipation from the films to the substrates. The temperature modulation can be further enhanced with the help of a simple suspended thermopile configuration consisting of two Ni strips separated by a small distance. These demonstrations will provide a guideline for the thermal design of thin-film-based spin-caloritronic devices.
