M. A. DeLeon, T. A. Tyson, C. Dubourdieu, A. Bossak, J. Dvorak, and G., Bonfait
TL;DR
This study investigates the magnetization properties of La0.8MnO3 thin films, revealing suppressed bulk and surface magnetization due to coexisting magnetic and nonmagnetic phases, with implications for magnetic thin film applications.
Contribution
It provides a systematic analysis of surface and bulk magnetization suppression in La0.8MnO3 films of varying thickness using XMCD.
Findings
Bulk magnetization suppressed up to 1600 Å thickness
Surface magnetization depressed in all films
Coexistence of magnetic and nonmagnetic components identified
Abstract
A systematic study the magnetization in La0.8.MnO3 films of thickness varying from ultra-thin to bulk-like has been conducted. The study reveals suppression of the bulk magnetization for films up to at least 1600 A. In addition, the surface (top 50 A) of all films exhibits depressed magnetization as observed by x-ray magnetic circular dichroism (XMCD). The reduced surface magnetization is attributed to the coexistence of magnetic and nonmagnetic components of the same chemical composition.
