Magnetic properties differ for x=0.5 due to structural distortion.

Abstract

High–quality epitaxial YNixMn1-xO3 thin films have been successfully grown on SrTiO3 (100) (STO) by pulsed laser deposition. X-ray diffraction studies showed that the films deposited on STO are fully c-axis oriented and exhibit in-plane alignment. The magnetic transition temperatures (Tc) of the films (both x=0.33 and 0.5) are equivalent to the values of the corresponding bulk samples. However, when x=0.5, the films show magnetic properties quite different from those of bulk samples. This difference may be caused by the structure distortion in these films.
