Image of FIG. 1.
FIG. 1.

(Color online) (a) X-ray diffraction patterns of undoped (black), Co (gray) hafnia films. (b) A clear shift in the (002) peak of the hafnia phase indicates dopant incorporation. (c) The full width at half maximum (FWHM) curves for undoped and Co-doped .

Image of FIG. 2.
FIG. 2.

(Color online) (a) curves obtained at room temperature on films grown at and show the occurrence of ferromagnetism, (b) No ferromagnetic hysteresis is seen in the undoped film deposited under the same conditions as that of above.

Image of FIG. 3.
FIG. 3.

(Color online) (a) High resolution -contrast transmission electron microscopy (TEM) image of Co-doped hafnia film showing epitaxial growth on YSZ. (b) The EELS line scans shown bring out the presence of Co-rich surface layer in top . No Co signal detected in the film. (c) establishes more clearly the appearance of a thin layer on the top which is attributed to Co-rich surface layer.

Image of FIG. 4.
FIG. 4.

Secondary ion mass spectroscopy (SIMS) data for Co, Hf, and Y. Note the rapid degradation in intensity for Co in first few nanometer regions suggesting the Co-rich surface layer in Co-doped .
