Gadolinium thin films as benchmark for magneto-caloric thin films

Helmich L, Bartke M, Teichert N, Schleicher B, Faehler S, Hütten A. Gadolinium thin films as benchmark for magneto-caloric thin films. AIP ADVANCES. 2017;7(5): 056429.We report on the preparation of Gadolinium thin films by means of sputter deposition on Silicon Oxide wafers. A series of samples with different buffer layers and various substrate temperatures has been produced. The film on an amorphous Tantalum buffer deposited at 773 K shows the highest increase of magnetization during the phase transition at the Curie temperature. Further detailed analysis of the magnetic properties has been conducted by VSM. (C) 2017 Author(s)
