Ok, this might be a random question, and Anime forum is the closest I can think of to this topic... so

I've seen in animes these spell casters/wizards that use a piece of paper with writing on it to cast a spell (they usually hold it between to finger and then throw it in the air).

What I'm wondering, does this have any reference in Japanese history/tales etc? Are these spell casters and spell papers called anything? How can I search for reference pictures online?

Also if you know any characters that do so, could you give me a suggestion?

Many thanks in advance!
