in some threads i find advice on mage battles that advocate the use of these anti-mage spells. however, spell protections don´t protect from area effects and most wizards have few enough hit points that 1 or 2 skull traps will make short work of them. the only spells of this nature i can see of being useful to any degree are those that reduce magic resistance... and even they are rarely efficient; dedicating the slot to a beefing/summoning spell would usually give better results and those are useful against just about anything rather than only a select class of enemies.
