Ferromagnetic ground state in La0.5Ca0.5MnO3 thin films

• Resistivity and magnetisation measurements were done with bulk and thin-film samples of La0.05Ca0.05MnO3. Bulk samples showed an antiferromagnetic insulating ground state as expected for this composition, whereas thin films demonstrated a ferromagnetic metallic ground state. This effect is attributed to the film adhesion to the substrate which prevents the lattice distortions necessary for the charge and antiferromagnetic ordering that occur in the bulk samples.
