    Abstract : We report on smooth high quality c-axis orientedNdBa2Cu3O7-δ (NBCO) superconducting thin filmsgrown on (001) SrTiO3 substrates using pulsed laser deposition.The transition temperature of these NBCO films was around 89.5 Kand the root-mean-square (RMS) surface roughness was 0.75 nm for150 nm thick films.

  4. 2. Generalised Ramsey numbers and Bruhat order on involutions

    Author : Mikael Hansson; Axel Hultman; Jan Snellman; Jonas Sjöstrand; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of two papers within two different areas of  combinatorics.Ramsey theory is a classic topic in graph theory, and Paper A deals with two of its most fundamental problems: to compute Ramsey numbers and to characterise critical graphs. More precisely, we study generalised Ramsey numbers for two sets Γ1 and Γ2 of cycles. READ MORE
