Does temperature effect how easily something is magnetized?

[Nathew]

Say if a certain substance is heated to 500 K is it easier to magnetize than if it were at any lower temperature?

Does temp effect the duration of magnetism?

In terms of temperature affecting magnetism, I'm pretty sure the domains will align in a better fashion if they are moving less (lower temperature).

In terms of temperature affecting magnetism, I'm pretty sure the domains will align in a better fashion if they are moving less (lower temperature).

But at higher temps the domains are more free to move and more easily aligned? No?

Whether or not the magnet can be magnetized more easily at higher temperatures is beyond me. I am rather sure, however, that cooling a magnet allows the domains to maintain alignment thus increasing it's strength.
