It is not referred to as such, but the shields she raises are intact barriers that look very much like the shields from a protection spell. It makes sense that Emma would trap MM, David and Regina between the two magical shields; that way, they can't enter the house and interfere with her plans and they can't run off and find something to break the spell. The way the shields form when she slams Excalibur into the ground is also very reminiscent of the way Cora created a protection spell by slamming a staff into the ground. So yeah, it definitely looks like a protection spell to me.
