Some would call that a cursive k, as it is similar it the handwritten script form. It's more common in italic serif fonts, like your example there. I can't think of a sans that has it off hand, but I'm sure one will turn up.

bree from type-together has such a cursive »k«, not only in the italic but also in the upright... here is the link: http://www.type-together.com/Bree

Parisine Plus italic has a sort of looped k.
Another one is Ronnia Italic from Type Together.

Pauline has a cursive/"loopy" "k" too, but it might be too scripty altogether.

FF Nuvo has such a "k", in the Stylistic Sets feature.

FF Strada has a beautiful italic with a looped k.

Another sans with such a "k" in the upright and in the italics is FF GINGER

Kaffeesatz is a sans with a looped k. There is no italic in the family.

Nevermind, I said the same thing Cerulean just said. Gonna go make coffee…
