The most efficient way to find academic articles on your topic is to use one of Drew's search tools. In this case, Scholar Search is a mixed bag, since it includes a number of popular sources, but also access open access resources. Google Scholar, although often useful, is not a good starting point, since its ability to pinpoint articles and to provide access to them is limited.
Most of these tools permit you to limit your search results to Spanish language material.
