The book The Russians in Germany: a history of the Soviet Zone of occupation, 1945-1949" by Norman Naimark has a good deal of evidence in the chapter "Soviet Soldiers, German Women, and the Problem of Rape." There's no mention of Stalin's order though, and it mostly condemns smaller units. However, it does quote Stalin's response to accusations of mass rape in Silesia as being "In every family there is a black sheep," a Russian proverb. That's on page 71.
