Abstract

A study of the properties of La 0.8MnO 3 films of varying thickness was performed. Transport and magnetization measurements show that the ferromagnetic (metallic) volume fraction of the film varies from ∼ 1/4 for ultrathin 60Å films to ∼ 1/2 for 1600Å films. Multilength scale structural measurements reveal that near 300Å, a transition from highly strained ultrathin films to relaxed bulk-like films occurs. The transition region is characterized by low surface roughness, high crystallite orientation, and broad d-spacing distributions.
