The "^" sign over the "=" sign

Question

I want to have the "^" sign over the "=" sign.

I have tried \newcommand{\defeq}{\overset{^}{=}}, \newcommand{\defeq}{\stackrel{\text{^}}{=}}, \newcommand{\defeq}{\overset{\^}{=}} and different combinations of these, but none have worked yet. Also, I would like my command only to work in math mode (in the {$$}, \begin{equation}, and such environments). I do not want it to work in textmode, so the output of \defeq , {$\defeq$} should be , ^= (but the ^ over the =).

Yes @campa. However, that post did not include how to make the command exclusively work in math mode. So it is not entirely a duplicate. — Vebjorn, Oct 29 '19 at 12:58
Sorry, I misunderstood that last sentence (close vote retracted). But why would you want that? — campa, Oct 29 '19 at 13:26

You can try \newcommand{\defeq}{\mathrel{\hat=}}.

Right! I've edited my answer. Thank you. – José Carlos Santos Oct 29 '19 at 12:52
\newcommand{\defeq}{\hat{=}} works fine. (I use the packages mathtools and amssymb (amsmath is included in mathtools). Thank you. – Vebjorn Oct 29 '19 at 12:55
But you did not explain how to only make it work in math mode. – Vebjorn Oct 29 '19 at 17:04
