@font-face in Internet explorer?

Hi guys,

I hope someone could help me with my problem.
I'm trying to get a special font in my css. Here's my code:

@font-face {  
		font-family: "Trajan Pro";
                src: url('default/templates/font/TrajanPro-Regular.ttf') format("truetype"); 
}  

In Chrome, Firefox and Opera it works, except for Internet Explorer.

Is there a special code, of a way I can make this work in Internet Explorer to?

Thanks!

Lotte
