I don't know those ones, but one of my fave magic animes would have to be Mahou Sensei Negima. It's also got a spinoff and three OVAs (and a live action series, but I haven't seen that)

slayers
shonen omnyoji
negima
cardcaptor sakura

(maybe someone will better answer than me...XD)

Try “Witch Hunter Robin”

I haven't really seen any magic animes. But my friend is in love with this anime called Negima! which has magic. Try and look it up
