Yes. They are master-level Conjuration spells called "Dead Thrall", "Flame Thrall", "Frost Thrall", and "Storm Thrall". The cool thing about "Dead Thrall" is that a raised corpse does not turn into ashes after they are killed so you can raise them again.
Right except your conjuration can be as low as 90.You need 100 conjuration, and then you talk to the conjuration master at the college (phinis gester I believe), ask if there's anything more to learn, and it will start a quest for the spells. Afterwards you will have to purchase dead thrall from him.
