Investigation of microwave losses in Nd0.67Sr0.33MnO3 films

The correlation between microwave losses at 13 GHz and dc transport and magnetic properties of epitaxial Nd0.67Sr0.33MnO3 films is studied as a function of film stress, which depends on thickness, at 20-300 K. Experimental results suggest that microwave losses in the films originate rather from magn...

Description
Summary:The correlation between microwave losses at 13 GHz and dc transport and magnetic properties of epitaxial Nd0.67Sr0.33MnO3 films is studied as a function of film stress, which depends on thickness, at 20-300 K. Experimental results suggest that microwave losses in the films originate rather from magnetic inhomogeneity than from uniform magnetization. Thinner ( < 100 nm) films exhibit higher magnetization yet reduced losses. 7 refs.
