      abstract     = {In the present study an advanced pillar splitting method is
                      used to determine the fracture toughness of a garnet-type
                      Li7La3Zr2O12 (LLZO) electrolyte. The obtained results are
                      compared to data derived on the basis of conventional
                      Vickers indentation. Furthermore, potential micro-pillar
                      size effects are investigated. The estimated fracture
                      toughness values for single grains and polycrystalline LLZO
                      material obtained via both methods are in good agreement,
                      yielding ∼ 1 MPa m0.5, hence the data indicate that
                      LLZO exhibits relatively low fracture toughness and has a
                      brittle behavior.},
